Rear seat bolts

[bluejim]

Hello, I'm currently swapping the third row ok an early 2000's yukon into my Jimmy. I'm utilizing almost all of the stock mounting hardware to make it easier, but I seem to have misplaced the two bolts that go into the hinges in the rear seat. I, for the life of me, cannot find a single bolt that fits in these. Does anyone have any information on the exact size of the bolts I would need? Thanks!

GM did crazy things American standard and Metric thread bolts and screws. Not looking at the bolts I don't have anymore, would guess one of theses.
