WTF is this? It's obviously neither M12(x1,75) nor UNC1/2x13...
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.

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

Desperate situations demand desperate measures. Might be worth
trying, thank you for the ideas.

1. The rest of the machine is mixed... I have encountered 1/2"x13 UNC,
M8x1.0, M27x1.5

2. That knuckle is second source.

3. The bolts from the worn out knuckle have 13tpi, about 11.7mm outer
diameter. But their threads don't look so good. I think I'd have
used them had they fitted properly, but I'll try them again. Easy.
REAL easy. And I'll take them to the dealer.

Yeah, shotgun it. What a simply Perfect idea!

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.

And, of course, try the bolts from the left hand knuckle ;-)
