Seat belt bolt question

[Cuda_mark]

I thought all rear seatbelt bolts for a 1970 convertible should be C11's, 7/16-20. My center rear holes are bigger than that though...probably 1/2. The floors are AMD. Anyone else had this problem?

The seat belt holes in my Dynacorn 6000WT (rear seat/trunk floor) were correct (7/16 x 20). BUT, my AMD side seat belt bracket was the wrong threads. Seems like AMD is encountering some quality issue.

I wish I had thought to check this beforehand. Oh well.
