i wish to replace every thing but the body and the electrical system and whats in the cab of my 1989 dodge dakota where can i get this done for the best price?

All you can do is shop around and compare prices at wrecking yards in your area and on-line as well as on Craig's List for vehicles being parted-out. If you are able to do so, doing the work yourself will save you quite a bit of money otherwise, you'd better have fairly deep pockets and a shop/mechanic that you trust. You also need to make certain that all of the parts bolt on without a whole bunch of difficulty as that could get real spendy, real fast. Good Luck! /r Martin
