Does anybody know the size bolts required (Grade 8.8) for the seatbelt locations in a 84 Carrera?

I have some 7/16 20 thread pitch bolts that are not grade 8.8 they fit and are fully threaded, but not sure what grade they are (grade 5 I assume).

My guess is since I cannot find them anywhere is that there is a metric equivalent to that size that fits the seatbelt locations.

I have found that size but they have a shoulder on them which will not work, I need the fully threaded ones.

Thanks -
