What size/thread pitch are the seat mount studs?

[sth5591]

I am ready to put my seats into my MJ that I've been building, the studs are there in the floor but I don't have the nuts. Anybody know off hand what size/pitch they are? I have a big bucket of bolts and nuts in the garage and nothing fits that I've tried.

They are Metric, maybe M8 or M10 (can't recall off hand) ...

Try m8x1.25
