shoulder belt anchor location?

Mine use C-11 seat belt bolts and I put a washer undernesth to keep the belt from bitting into the headliner. The hole should be about 3/8" in diameter. When threading thru the liner do not let any of the liner get into the hole as the threads on the seat belt bolts are real shallow and can get messed up easily if you do not get the bolt properly started. Been there, done that.
