Re: I've lost count - 1988 GMC S-15 Base
From what I have understood, the speedo issue is not just a simple tail shaft swap.
From what I've seen, the mechanical speedo connection is in a different location on the tail shaft. The mods I have seen included welding the e pickup hole shut and relocating the hole for the cable drive forward. You then need to locate the bevel gear in the right spot on the output shaft.
I have that clean 82 long bed with a 5 speed e speedo tranny. Someone swapped the fiver for a 4 speed that was in it.
I looked into it, it's close to 300 pesos to correct the issue (tail mod).
I'm probably going to buy a GPS speedo generator and connect the cable speedo to it.
No worries about gear or transmission ratios.
It's about $150 IIRC.
Truck is looking bonkers. The fade is way cool.
Cleaned and dropped really well.
Wait... isn't an 88 electronic speedo?
