Re: My Build Thread (year+) on 71 Jimmy 4x4

Ok this thing needs a doubler, and Ive had a hard time finding a good used deal on a np205 with the 32 spline from a th400. That's what everybody calls for...ORD, NWF etc.

My truck had the 27 spline th350 style np205 stock, and so the bearing is smaller and to change the input shaft would be a pain or more expensive than waiting to find the right transfer case.

While back I found a Th350 style Np203 and adaptor, so I know i can mount the range box to my Th350....

Well i found a very cheap 205 from an 86 chevrolet 1-ton that was mated to a TH400. Looks to have the 32 spline long input shaft (would have to be changed for short shaft), and I guess a slip yoke rear output. It also has some sort of PTO that ran a 12k generator. All this stuff works flawlessly and the date on the 205 is March 13th 1986.

So now I have all kinds of crap, any advice on what I need or don't need to make the doubler? Anybody know anything about this style or brand of PTO?

First 3 Pics are the 86 np205, 4th pic is the 203 and adaptor, 5th is the stock np205 and 27 spline adaptor
