1985 std cab. Anyone know where one could find the size (size and thread pitch) for cabin bolts? I need them for the dash to A-pillars, and then the bench and seat belts. Some are SAE - some are metric. I can try to fit old bolts but want to know the correct size so I can run a tap through it and clean them up. No idea where all mine went.

4-bench seat bolts
3-seat belts to floor
2-seat belts to shoulder
3-dash to a-pillar
4-body mount boss on cab (1/2-13?)

Someone probably has this memorized. But I’d find one of each that works and then go to the hardware store with a list
