No problem Marty - I appreciate the pictures and help. I did look at my coup with the original trunk pan in it and saw the dimples for the 3 locations, including the one for the standard spare tire location that was used which has the holddown strap welded in place roughly centered between the 4 dimples. Looks like the convertible dimples are stradling the furthest right reinforcement rib about 6 inches toward the rear from the front edge of the rib and are oriented with the widest dimples toward the front of the car. Given this orientation, I assume the convertble holddown is supposed to be centered but toward the front side of the car from the narrow dimples, stradling that rib, does this sound right?
Any suggestions on how to create those dimples in my replaced floor pan? The ones up high for the space saver are still there, but not the two lower sets, as long as I am in there figure I would try to dimple it to look correct.
