Seat belt bolt sizes - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I recently ordered a Retro Belt system for my 86 Custom Deluxe. The previous owner removed the bolts where the buckles are with no issue, but broke off the bolts where the retractors are. I drilled and tapped those to 1/2" so I'm good there. The threads on the buckle bolts need to be cleaned out, but I know they are not 1/2". They provide a couple different sizes of bolts in the kit, but none of them seem to fit. I thought they had switched to metric for these bolts, but I'm not sure what size they are. Any help?
