yep...http://<strong>www.4wheeloffroad.com/techarticles</strong>/drivetrain/131_0505_np205_transfer_case/index.html


Performance Gear & Axle has a great reputation for unique driveline combos, even mating a Clark five-speed to a Dana 300 transfer case or an NP205 with its own line of adapters. In fact, the company even offers reproduced factory style adapters for the hard-to-find TH400- and TH350-to-NP205, and even one for the never-produced 700R4. but wait,..theres more!

Teckpak Fitzall (brand name) Quick Swap spacer. Part #7Q-35A. This is the cast
aluminum spacer that allows “no output shaft changes” to the 700R4. Using this
spacer allows you to use any 700R4.

 

One important thing here though, make sure you use a 700R4 with a HD cast case. While most 700R4's used in 4x4 had the heavier case, some did not and since the tranny absorbs all the counter torque from Tcases reduction you want strongest case casting on it. It is easy to tell the HD 700R4 casting though. They are the ones that have a bolted on lower torque converter cover that is cast not stamped. Also, make sure you use one with a 30 spline input shaft. The early ones had a 27 spline (pre 85) and are to be avoided unless they are being rebuilt and brought up to current spec.
