Re: Seat bolt size and thread pitch?
If you mean the bench seat brackets to seat and floor, (GR 5) 1/2" hex recessed head tapered bolts with spin washers. The bolt threads are 5/16-18 x 7/8" under the spin washer, and the heads are stamped RBM.

Much of the info. applies to all 67-72 GM trucks, and to a lessor degree all 67-72 GM vehicles. My build thread, and more on the guide https://67-72chevytrucks.com/vboard/...d.php?t=730025
