AZ WTB-NV4500-Bellhousing-NP241

[83GMCK2500]

External clutch slave cylinder is 92-94 with the oddball bellhousing to trans bolt pattern. GM input shafts are all 1-1/8" 10-spline with a pilot snout diameter of 0.590". The 4x4 NV-4500 has a 32 spline output shaft. Look for an NP-241 that is behind a TH400 or 4L80-E to find the correct 32 spline input gear.

Worthy to consider: Build the correct case from 2...go ahead and find a driver's side drop case from an IFS truck that has the 32 spline input gear, then source a 241 from a square body, split it and put the correct gear in.

I am collecting parts for my NV-4500 swap, so I've researched as well. I started with a 2WD trans and I've collected the 4WD tailshaft, I need the Mainshaft, the balancer, a spacer, and a couple little internal doo-dads + whatever else my trans might need in R&R. I removed it from a '93 C3500 with a seized 6.5L-TD so I didn't get to test it. I have 2 NP241s, both of them out of 90/91 squares with Electronic VSSs, one has 27-spline input from a TH700-R4, the other is the correct 32-spline from a 4L80-E.

Need trans parts? Looky here, they have good used & tested parts for decent prices: http://www.tbtrans.com/transmission_parts.htm
