Screw thread size & pitch - seatbelt guide screws

Does anyone know the screw thread size and thread pitch for the screws that hold the plastic seatbelt guides to the top of the front seat backs?

Jeff, I took one out of a spare seat and it looks like 16 by the thread gauge. It appears to be 1/8" x 3/4" using the trusty ruler and drill index.

Thanks, Dan. I havent had the belt guides on for a few years as the old ones were cracked / broken. I just got hold of a pristine set of guides, and couldnt find the old screws after an extensive search of my piles of car parts. I know I saved them...... somewhere.

Jeff, it appears to be the same as the rest of the interior trim screws. Black, phillips, 3/4" long, 16 tpi.
