The farther and farther I got into the initial sanding the more apparent it became that this is not going to be a quick 20 ft primer job. Major repairs discovered. So I shot it with primer so it looks ok flying past at about 30 if you have bad eyesight and are blindfolded. This AM I started putting it back together.  This was a bad idea!  After my move I'll get a better handle in what the body needs and have a pro do the job, way too much for this hack.

The T Top lock plate(rear) backer can be recovered by LOOSENING the interior vinyl trim piece where the seat belt/retractor go thru..Six black phillips head screws ARE REMOVED..and the trim is moved downward and toward the interior a bit so you can see behind it easily..Then you'll probably find the steel backer inside the area right above the rear of the door jamb..Reinstall the T Top rear plate and check the fit..Don't forget to put a thin layer of the 3M double sided tape between backer plate & body for water-sealing.. IF the T Top fit is good and snug..and if all is well, resecure the interior curved vinyl trim..Adjustment of the snugness of the T Top is simply done by screwing the threaded lock down knob in the front in or out to loosen or tighten..It's on the open-close lever mechanism..Jim
