Anyone know the hardware size of the nuts and bolts used to attach the front seats to the brackets? NOT the bolts used to attach the brackets to the tub.

I misplaced the hardware I pulled off. Needed to replace them due to rust anyways.

I looked for their size in the Mopar parts guide but it doesn't show them. It shows the seats, then on a different page it shows the bracket/base the seats bolt to. But no bolts are shown to bolt them together. At least none that I could find.
