Hi all does anybody know what the thread size is for the seatbelt bolt that screws into the sill Please.

I'm pretty certain it is a 7/16" unf thread. the part no. is 9288604, it appears to be gm's global standard thread.

Get a impact gun with enough torque and thread size and pitch is irrelevant.
