1987 GMC V1500 Sierra Classic LS swap/build

[Flatpat]

I used the Advance Adapters brand (same basic mount as diy4x) on my jimmy and they lined up everything just like it was before but I reused my transmission. I don't know with you using the new transmission how much adjustment you would need or if you would have to change shafts lengths.

I am under the impression that 700r4 and 4l60e are same dimensions. They are both 4x4 and I'll be using the transfer case from a 91 big blazer. Np241 I think.
