Swapping a 1st gen chassis onto a 70’s style frame?

My little brother got a 99 regular cab 2rz 5speed with a rotten frame.

a friend of mine is giving me a 70’s style pickup with a bunch of trail gear stuff, air lockers yada yada.

anyways, i was wondering how possible it’d be to swap the cab and motor from the 1st gen onto the 70’s frame?

should i keep the 20r trans or get one from a 22r/re?

is this just a pipe dream?

i can put it together and wire/weld whatever no problem, i just want to develop a game plan and get all the right parts together before we start taking stuff apart.

any help or 2 cents would be very much appreciated.

Anything is possible with money, cutting, and welding.

 

Yeah if you gotz teh tools and skillz anything is possible . . . . a short real life parable . . .

I knew a guy who took a Vega, put a Chevelle diff in it (I think, it was a 6 bolt anyway) and stuffed a V-8 under the hood, required lots of mods. The real problem?

Every time he saw a girl on the street he just had to gas it . . . broke the distributor shaft off against the firewall. Every. Time.

Moral of the story is, besides the challenges of making it work, what else might you encounter you never would have thought of?
