I also have a 95 G20t that I'm putting up for sale soon. Has a RR motor as the original motor crapped out before I bought it. Hit a deer last year, so the hood and pass front fenders are no longer the same color, and the roof is starting to fade. Tranny has pop out. It has new axles and seals in the trunk, I was going to put a rebuilt tranny in but sold it to Rodney instead (the tranny). Still runs great and gets mid 20's mpg with only the 4 speed. I'm not sure how much you were looking to spend, if you have interest, pm me for more details.
