It does depend on what you want to do with it in the end, if you just want a driver without any hauling capacity a car suspension would probably be ok. The first thing that you need to do is take a tape measure to the possible donor vehicle and see if it is too wide. Most are and it will look very goofy if left alone.
I suggest finding a chevy 1/2 ton van (73-99ish)and using that chassis. it will be too wide, but you can narrow the front cradle without too much trouble, you will have to narrow the center link too. all other parts stay factory. this way you have a 'coe' steering and somewhat robust suspension but can still ride nice.
I will have to look, but there are a couple of people that have done a show and tell on narrowing the 73-87 front suspension cradle, works very well.
