What is the correct bolt size and thread pitch for the inside spare tire carrier?

Thanks

Member 71K5Randy had them for sale for several years (He is Sold Out now) It says this.

These were a unique length (6-7/8”) and fine thread (7/16-20) carriage bolt that would accept a lug nut.

Sorry I wasn’t more clear in the original post. I’m looking for the correct thread size for the four bolts that mount the tire carrier to the floor.

7/16 fine thread, same bolts that hold the front of the rear, the originals had WB on the head.

That should have read front of the rear seat.
