Spare tire bolt thread

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

Thanks

Re: Spare tire bolt thread

This thread link below:
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.

Re: Spare tire bolt thread

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.
