I work at a very small shop and we work on the tow trucks for the Houston Auto Auction and they are always trying to pawn off all kinds of stuff onto us, I can ask if they have something like that
try http://www.pullapart.com/ might not have one in your arear but its worth a try....you pull the parts you need and they are cheap as hell and 99% oem and in great shape...plus you can pick and choose which parts you want off mulitple vehicles of that type and arent stuck with what they pull and give you...worth a shot...i can even look for you here and see what they have here and maybe work a deal to get them to you since they are so easy and cheap to get...
excentrick, thanks dude!! i guess i should be mad at you since i've spent the last 3 hours trying to find the perfect wrecked donor, but i have a lead on 3 good ones. I just wish they put 454's in tahoe's, hahahahahahaha
