Don,
what T case do you have? My S10 has an NP207 with a slip yoke.. I am thinking about throwing in the front half of a NP231C and doing a D300 flipped and bolted to that for a doubler.

i have a 231/241 doubler. i assume you are talking about d&d's doubler, thats what i have. if you run the 300 behind it, you have to flip the first case to clear the driveshaft. but its a common enough swap and you can find all you need to know on the pirate threads.

[poriggity]

If I do the D300 doubler, I will either use the doubler kit from D&D, or madrooster off road, and I will get the flip kit from D&D for the D300...

i have the d&d, and i like it. i dont know anything about other kits, but d&d is very good quality and i will vouch for it. i havent run it yet, but i like the ways its made.

you might have to change the hole output shaft, and if your doing that you might aswell just put a 231 in it that already has the fixed yoke and the manual shift.


one more thing, count the mounting bolts while you are at it. i want to know if it is 5 or 6

[Tim99Zr2]

fvck didnt want to put a new tcase in.. oh well its got to be done.
ill prob look into it this weekend for you don

good thing im gettin a second job next month haha

keep looking. its either a 203 or a 205 and its on the wrong side.

[Tim99Zr2]

shit.. haha. just thought i'd ask its for 25$. you know a quick list of ones i can use? or should i just get a 231?

[Tim99Zr2]

85 chev 4spd trans and tcase for 500 obo.

but its passs side drop too?

yeah, thats a sm465/205 its a good combo but any full size older than 88 will be pass drop. and $200 is too much for that combo let alone $500

[Tim99Zr2]

son of a..... haha.

what is a good case to look into getting?.

[Donahue]

if you have a 5 bolt, then get a 231c. if you have a 6 bolt (ive been told 98 and later do) then get a 241c

[Tim99Zr2]

hmm. ok thanks don!

[Tim99Zr2]

are the bolt holes where it mounts to the trans?

[Donahue]

not where the adapter mounts to the trans, but where the t-case mounts to the adapter. one thing, you will need to get the shifter for the correct t-case. you will also need a different rear driveline for the 241, it has a 32 spline rear slip yoke verse 27 spline that the s10 case has.

[Donahue]

if you get a 241 from a 1/2 ton, it is likely to have the same u-joint size and all you would need is the female end of the slip yoke, and you could probably put it on your current driveline.

alrighty, ill check that out. and..
holy shit.. now i need a new slip yoke for the rear too
and the shifter shouldnt be too hard to get?. it may even come with the tcase?

i think i might try to figure something out for the front. haha or have a 2wd sfa truck

but time for work in 15 min, so i duno if ill reply again. thanks don!

[Donahue]

you could see what NC did, i believe he also has the same setup as you do, and he claims to have good flex.

[Donahue]

[Tim99Zr2]

im thinking i can make a bracket or something to keep the front shaft from sliding off the t-case.. ill have to search around, and thanks for the link donahue, ill check that out

[Tim99Zr2]

hopefully nc will chime in before i get off of work with some info!

Limit straps... or chains whichever you prefer.. gonna be putting them on mine when i 4link it

The rear is just a longer driveshaft with the same slip yoke.
At full droop, the slip yoke won't come off the output shaft.

On the front, for now anyhow, I had access to a slip yoke that had a been drilled out for a set screw. I ground a "V" into the splines of the front output shaft, put the set screw into the slip yoke, and tightened it down enough to where the driveshaft would pull apart before it ever began attempting to pull off the output shaft.

If any of that doesn't make sense, just let me know.

There isn't much "claiming" to it. I've known for quite a long time just how well the setup flexes.

[Tim99Zr2]

AWESOME nc. i completely understand that. ill have to do that.

what size screw? did you groove the whole way around the shaft? if i could get more info on that please. and get i get a pic of your tranny cross member? for the third time.
thanks

[Tim99Zr2]

so i think im back in the game for a square DS. on my way home from work i stopped on the bridge and left my truck crawling in gear and seen that my yoke on my front diff didnt spin... since baggey didnt tell me!

[Baggey22]

I didn't think you needed me to tell you anymore since Donahue told you last night that it wouldn't spin with the vacuum disconnected.

[Tim99Zr2]

oh, well i found out anyway.. just wanted to look

I'll see what I can do this week. It's suppose to snow quite a bit (so they say ) tonight and tomorrow, so I don't know if I will get to it right away but I'll see what I can do.

As far as the set screw, it is maybe 5/16ths or 3/8s thick, I guess. You don't have to grind all the way around the shaft because the "V" should be deep enough (relative to the set screw, not anywhere near 1/4 into the shaft at all haha) to where the set screw will not allow the slip yoke to travel forwards or sideways for that matter. Only issue I may could see is if the front square driveshaft gets caught on something, it may cause the set screw to want to move on the output shaft, but that would probably be quite rare if you notched well enough and tightened the set screw well enough (with anti-seize of course).

[Tim99Zr2]

oh you puss. learn how to drive in the snow! haha.

yea i def think im going to do it this way. how will i know where to groove the output shaft? maybe drill and tap the yoke, slid it on, put paint on a bolt head, run that in until it touches, back it out, pull off the DS and have a paint mark on the output shaft... hmm?

but yea, thats a good idea, dont you already have a pic of your tranny cross member, i know i seen it before. ill go browse your thread!

EDIT: its not in your thread.. i know i've seen a pic of it on here!!

[Donahue]

did you repaint your truck NC?

[Tim99Zr2]

thats not his. that one is 98+ and fleet side, with different sliders, tires, wheels

[Tim99Zr2]

ok, so i think my front drive shaft needs to be roughly 28" at ride height.
im planning on getting square tube of. 2x2x1/4" at 16" and a piece of 2.5x2.5x1/4" at 18" long along with 8-10' of 1" Sch. 40 pipe for my shock hoops and tranny crossmember.

going to get a price now. think the DS lengths will be enough?

[Geoff03]

no thats steve's truck from zr2usa...its going one tons now. and 42s. and it has a cage now, and flat bad. plus it actually gets wheeled

this is how i figured our last sq one. take your yokes and figure out where you are going to cut them off, and how long they are from the u-joint center to the cut. something like 3" is what i would expect. now flex your drivers side up to full compression and measure that distance from your yoke to yoke. this tells you how short it has to be able to go. say that is 26". now take your measurements from before, add them together for both yokes, and take that off this minimum distance. now we have 20". then take another 2" or so for safety and you have 18". now if you had two pieces of square tube that fit inside each other and were 18" long this setup would be about perfect. one more thing though, when i did it i forgot to take into account the part of the yoke that went into the larger square. if you do it that way, make sure you take that amount off the smaller tube's length.

does this all make sense? measure what the minimum needs to be and go from there.

[Tim99Zr2]

meh, thats alotta shit. i bet if i read it ill understand it!

i was just eye balling it, guessing lengths with it sitting in my drive way. but ill do it that way tomorrow donahue!! thanks again man.

this truck is going to need some 3leaffab stickers. i think you put as much work into it as i did

EDIT: i get it now!

Is that the one you are thinking about?

[Tim99Zr2]

exactly it, thank you!

so im going to get my shock hoops and tranny hoop bent up tomorrow. and i also think i am going to get my driveshaft material!

for my hoops i may have to bang an amish chick thou, could make an easy 200$ on top of them bending my stuff!! (yea, the amish are going to bend my pipe)

If you want to PM me I can give you info to contact me, if it would be easier that way. It's up to you, I just figure I can explain it easier, quicker, and less painlessly that way.

just needed a pic, thanks for the offer thou
what'd you do for exhaust?.. ugh

[NC4x4]

The main reason I said I will try to get one after the snow is gone is because I'd have to get up under there pretty good to take a picture, and the ground is still pretty nasty for the time being.
I had all new exhaust put in after I ran practically "open headers" there for a handful of weeks. Got the drivers' side pipe tucked pretty neatly under the transmission and then had the back in look like this...

[Donahue]

fancy shocks

[Tim99Zr2]

hmm, looks like ill deal with the exhaust too. haha. dammit. this is alotta work!! thanks for the pics man, they help!

i can get a ford 9" here for 50$ i wonder if i should grab it? someone had 2 for sale locally

28 spline? 31 spline? full width?

[Tim99Zr2]

i dunno. ill send an email, and call tomorrow

guessing i'd want 31 spline, but i dont think id want full width

[Baggey22]

the 9" may be full width, also the gearing may be off, and your bolt patterns will be different. . . again.

[Tim99Zr2]

fvck, nevermind i just found a FF 14bolt with 4.10s!! 150 OBO?

out of a chevy, 70's 1ton
