I have a pair of steel car ramps up for grabs - free. They ARE NOT suitable for the RX-8 (or I'd consider keeping them) as the lower lip of the bumper hits them.
I'm just cleaning out the garage, trying to find space to stick my 8 into it, and I've not used them in over 6 years...so they can go.....

PM me ( may be next week getting back to you, as I'm pretty busy this holiday weekend and going on vacation for the rest of the week.)

Still available...Goodwill won't take anything "car related"
