Newbie with 59 apache project

[Okla'59]

I have been lurking around here for awhile. Decided to just ask my question.

I am wanting to graft in a subframe to my truck, but i cant find a definitive answer on the donor other than a valore (which i cant find). I have at my disposal a mid 70 and late 70 full size pickup i can use, or a mid 70 chevelle also a pinto (was told that this would work with ALOT of fabricating). I just dont have the funds to go out and buy Mustang 2 IFS.
