did our 71 with a full lining from TMI but had problems as the grippers over the doors had been ground off flat. not perfect but acceptable, was dissapointed at the cut of the TMI set as parts were not cut to shape just sheets, only good bit was the stitching for the rods on the liner, instructions were piss poor even to the part of identifying what the bits were.
used a few web sites for info
