BTW the GMC version is a drop out type . Find one of those and save a bunch of time .
I still have to cut and modify this one so the 4L60E can be serviced .

i consider this very important. my truck was cut out and had a sbc scabbed in, as wrong as possible. either make the drop out or fab something else to support the cab or the cab will sit on the frame, not the cab mounts.
this is my version of a support system, very similar to what the custom frame builders do
