I have a 68 malibu conv. The frame is in need of some fixing. There are several broken parts that are hindering me from hooking up the power top. I have to fold it down by hand or else it gets stuck and twisted. Does anybody know of a company that makes brand new or restored conv. top frames? Fixing this one would require welding and one part may be unfixable. It would be great to find a remanufactured top frame. Do the frames through 72 fit the 68? Thanks
