Buy the whole truck would be the best option. Then you can sell off what's left. You might even be able to make money on it. The downside is that you need the space for the truck but you're assured all of the OE pieces you might need then some. You'll have to figure out the exhaust. IF you're in an emission state then you'll have to check your local laws. Going with a OBD-I means there will be less computer controlled stuff and a lot less emission stuff. It will probably have a single car instead of a bunch of pre-cats and a cat. Worst case is getting one with dual exhaust with two of everything.
thanks jeffy, that actually made a lot of sense...i don't know if it's cuz i'm wasted out of my mind right now, or cuz it is logical, but as for the emissions state, the car is registered in PA, so i'm not sure whether i'm regulated like cali or not. less computer stuff means good scheisse for me, since i'm new to this and all. i do have the space for the donor truck, the only question is do the local yards have it, and if so how complete is it...i can borrow my dad's tahoe for the drag from the yard to my jeep's current resting grounds. btw, on top of the best top and the 31x10.5's i have added the sound system, 2x 12" subs, 2x 6x9"s, 2 3x5" or whatever the stock front speakers are, plus two amps, all from polk audio, with an alpine head unit. sound systems are the only thing i do well on vehicles, so i'm hoping i can manage to do as much of this swap myself as i can. i've always been good at taking scheisse apart and putting it back together in a working fashion, so maybe i'll get lucky, who knows? hopefully i can learn a thing or two about mech work in general from doing this swap.
