What are the bolt sizes for the two bolts circled in this picture? I’m having trouble...thought I found it but maybe stripped one...

Is the one on the right where the seatbelt hooks the SAE one? I read something about that but wasn’t sure.
Thanks

Just bumping for some help. If it wasn’t clear from that picture, I am referring to the bolts circled here:

Front bolt is M10 x 1.25 x 50mm
Seat belt is 7/16 x 20 x 1". Obviously, you want grade 8.

Fantastic! Thanks a ton. I hope I didn’t ruin one side of one seat by trying an M12x1.25 that I thought at first was correct. Will see...

Thanks guys that makes sense. I think I have the M10 bolts from when I disassembled, but can't seem to find the SAE ones. I'll pick some new bolts up just to be sure I have the right ones.

SAE UNF 7/16 - 20 is supposed to be interchangeable with M11x 1.25. That's probably one reason the Federal Motor Vehicle Safety Standards selected that particular diameter and pitch.
