I measured the ones that came with my Mopar skid. The manual says they are M12 bolts. I measured a length of 1.5 inches and the head of the bolt reads M(inside of a hexagon) 10.9. I also used a 19MM socket on these.
Again, they're yours if you want them/can't find a suitable substitute locally. I'll mail em to you if you like. I reused the ones from my hitch when I installed so these are fresh from DC.
