    If I should ever need a new 'case, can I bolt a passenger-output NP 241 directly in place of my NP 208 in my application easily?

    Did they ever make a passenger side output NP241?

    Keep it simple!

    They may have on the 88 and newer blazers and surburbans. I really don't keep up on the newer stuff.

    Keep it simple!

    Yep, that'd be where they came from, 88-91 Subs and K5s.

    I think the NP241's started being used on the K5's in '89. I just went out and checked the tag on the t-case from an '88 K5 that's on the garage floor. Says it's a 208C1. [​IMG]

    My 1990 has passenger side 241. The 2.72:1 low is envied even by Atlas T-case owners....Well maybe not. I am not sure about a bolt up swap, but I am sure Advance Adapters makes something.

    Real four wheelers don't need tools to remove body panels, paint, tail lights..etc.
    P.S. Ask me why it is called "BODY SNATCHER"

    Nobody knows? Is the input shaft the same or what? Obviously the tranny's the same.

    89 was the year the 241 came to past in K5, passenger side output with flange mount.

    If you ain't hurt, you ain't playin' hard enough.

    It is a bolt in swap. Just be sure to get the same version 241 as was your 208, as both used 32 spline inputs when behind a TH400 trans, and both used 27 spline inputs when used behind a TH350 or 700 trans.

    Cool, thanks a lot.

    I'm considering swapping to an SM 465/NP 205, but if I keep my 700, I'm going to put a 241 behind it.

    I really like the idea of an SM 465/NP 205 combo with bigger tires to kill my 4.10 gears. Maybe 37-38s.
