I just received a box of 50 molding fastners that will work in the rear trim of our GTs, they are a one inch stud mounted on a 5/8" platform with a hair spring attached to hold them in place in the channel of the trim. The only thing is they are a 10-24 thread, but if they work, which it appears they will I can do with a non-metric fastners in my GT. Anyway, as I said, I got 50 to a box, so if some needs any let me know by PM.
