Seat belt bolt

What size and length bolt is used to hold the passenger side seatbelt into the floor in a 70 gs.

 

I believe they are a special shoulder type bolt but not 100% sure but they are on my 65.///////

 

Oh do you have retractible belts or standard ones?

 

They are the lap belts and are retractable.

 

Outer ones next to door sill are about 1.25" long and 1/2-13 thread....chase the threads on the bolt with a die and use a tap to clean the anchor.

Ones that mount to d-shaft tunnel are about 2"
with a shoulder on them to allow the belts to rotate.
