This would be a nice project for someone with the space to put it. It looks pretty complete and not in bad shape at all for the age. I don't know a whole lot about the transmissions on these so I'm not sure if the thing being stuck in reverse is a huge deal, but I'm sure somebody on this forum with all the great knowledge could fix that easily. :thThumbsU
