There was a guy on
www.LS2GTO.com who bought one and was loaning it out to folks who needed to do a fender roll. It's been a long time since I have seen any threads about it, so I'm not sure if it's still being passed around. All he asked was that the receiver paid for the shipping. Several guys used it and there was, last I checked, a waiting list.
You can do a search over there and see if it is still available, how long the waiting list is, and if they mind if you use it. If it's still available maybe you can get in touch with the owner. I'm not sure how much the shipping was...
Good luck
Edit: Looks like the tool is still making the rounds. I did the search. The guy who owns it is Snafu. Here is the tread he started. Looks like it's 40 bux to rent it.
