Anything AE, you can find there^^^.
As for the differences from a truck today and one from several years ago...
with AE, there may be some very subtle suspension geometry differences...but being a basher, you wouldnt likely notice a real difference. I did not look at the link you posted, but someone mentioned that the AE GT in the auction was one of the tub designs? Im sure there would be handling differences tween that and a GT from today...but again, it won't really affect you. Good luck n hope both trucks turn out to run well.
