I am putting the 700R-4 into my 82 GMC, I have had the shorter output shaft for a while, and decided to let a shop put it in for $160.00.. I was told I did not need a adapter or anything for the swap, the 350 in there now has alike a 2 inch adapter, But I know I am not going to reuse that. Now before I do this, I just want to make sure I don't need anything else. I was told the trans, will bolt up directly to the transfer case with the shorter shaft installed, and I need no adapter, I think my 82 came with a overdrive anyway, because it has overdrive indicator on the dash. does all this sound correct to you guys??? those of you with 700's, will you see if it just bolts up to the T/C, and let me know, so I don't run into any surprise.
