tranny swap help

[jacksonbuilder]

hey, so thanks for any help or advice in advance. I have a 1990 blazer with the 700r4, my 2-4 band is blown so time for a new tranny. I also have a parts truck 95 s10 2wd with the nv3500. so I was thinking of just, move the nv3500 to the blazer. I'm pretty sure the bell housing will be the same from the 4.3 to the 5.7. I know I have to change the tail housing to accept a transfer case and maybe the output shaft. what I really need to know is, what are your thoughts, is this a good idea? is there anything that i may be missing? i have already taken the clutch petal out and mounted it to the blazer. i plan on just sticking with the same hydrolic clutch. any tips, advice, hints, or thoughts would be greatly appreciated, thanks guys.

IIRC, the NV 3500 output shaft change requires complete, and I mean complete, dis-assembly of the transmission. The extension housing is different between 2x4 and 4x4.

It would be so much easier to rebuild the 700R4
