Can someone tell me which seat belt bolts for 69 B-Body? C-10, C-11, C-12?

[GearAddict]

I've been looking for seat belt hardware for my 69 RR with bucket seats. One of our fellow members has 3 different types available but can't help me with how many of each I need for my model.

Appearantly they are marked C-10, C-11 or C-12 on the head of the bolt.

Can someone help me out?

Thanks again in advance...everyone here at FBBO has been a huge help.
