Hi Shawn, we have bolt charts available on the site: https://mtfca.com/phpBB3/app.php/gallery/album/195 which will give you most bolt (and nut) sizes.

The one you want is: https://mtfca.com/phpBB3/app.php/gallery/image/1501

and you are looking for a 3/8" UNF 13/16" long

The holes in the pan are tapped for 24 tpi. Check it out

The two bottom ones are shorter, threading directly into the pan. The two upper ones are a bit longer, going through the holes in the hogshead and then getting castle nuts and cotter pins (although a lot of people shortcut with lock washers?).
I don't recall the actual lengths (pretty easy to figure what fits best?).

Thanks everyone that really helped. I bagged and tagged everything but I can't find these ones. I'm sure they are somewhere safe.
