I seem to attract rusty, disassembled convertibles. This one has the front frame rails and the driver's side inner rocker removed,.floppy doesn't begin to describe it. As I have repaired several chassis on this fixture I continue to upgrade and build more sophisticated alignment fixtures for different areas. It is constructed out of 4" square 3/16" wall tube with threaded adjustable main attachment points and slide style removable adjusters for the rear. I built it to be very strong and easy to get around, definitely not a one time use investment.
