Is there an UNC15/32x13? Or even a cross-over 12mmx13TPI?

Go to a good hardware and buy every size bolt that even remotely looks like it
will fit. Carefully try each one. Check other bolts on the machine. It is
very likely that another bolt on the machine is the same size. Find another
bolt from the machine that will fit, take it to a good hardware supply or an IH
dealer, and have them match it up.

Yeah, shotgun it. What a simply Perfect idea!


If the rest of the machine is metric, it's not likely that this hole is SAE, and
vice versa.

My friend's daughter's Chevy V-8 intake manifold was a 2-piece deal,
plastic (FRP) and aluminum. One piece was SAE, the other all metric.
I think it was a 2008 model Tahoe. Unlikely lives at GM.
