Look this up on the H.A.M.B. (Definitive S-10 Frame Swap Vehicle List) it might give you some help
Indy is right on the Lists on the HAMB but if you are going for a swap I suggest you just measure your wheel base and google it .. you will find all the vehicles with the same wheelbase and you may find some interesting ,and inexpensive possibilities
If going original a complete parts vehicle is the way to go , you may also find that the donor is better than what you have .
Also a Lot of the ""S-10 swap kits" listed in the HAMB posts are no longer in existence
Good luck
