what is the spline count on my stock rear end? will the richmond 373 gears work in mine for a 2 series or do i need the set for a 3 series carrier. my truck originally had 342s and i had the 373s from slp put in and when my driveshaft broke it bent my pinion. i was in a hurry to get the new set so i ordered on summit the richmond gears for a 2 series carrier pn # RMG-4900071 i think i need the pn# RMG-4900461 for a 3 series. they are also both 27 spline. i need my truck back ASAP. thank you

You need the 3 series gears.

If you can use the Zexel again it is a 3 series carrier.

If you are using the original carrier it will also be a 3 series carrier.

The axle spline count only affects the spyder gears.

If your Zexel was not hurt you have no problem.

MAN i hope the zexel is ok and its just the pinion. what a pain this is. dont want to know what the bill is gonna be for all this.
