The Stovebolt Site Forums The Shop Area Paint and Body Shop What size are seat track bolts?

I reached out to LMC. They replied and said the bolts are actually coarse thread, not fine, but are not telling me the bolt size.

Since I already tried a 5/16" coarse bolt, maybe I'll pick up the next bolt size down which I believe is 1/4" and give it a try. This is crazy!
