Default bolt/nut size for seat mounts

I am working on a new seat mount for my racing seat, but havn't been able to figure out what the bolt size is for the OEM seat mounts. I tried 3/8" but it only scews on part way. Is this some funky course thread metric size?

Thanks

It is definitely metric. Just about every bolt and nut on the C5 is metric.

Hello

If the bolt are about 3/8. The correct size in 10mm x 1.5 pitch. You can buy them at a good auto parts store or hareware store. Good luck.

:iagree: That's exactly what it says on my parts CD. FYI, the GM part number for the nut is 10255857, but you can probably buy 20 of them at any hardware store for what a GM dealer will charge you for just 1.
