M10 x 1.25 pitch 40mm in length but they aren't just a straight stud they have lobes part way to stop threading in vs bottoming them out. I have a few extra new and a few used from my header job if you need some. I'm in Indiana too, south of Indy.

I had written down the part numbers awhile back for when I replace my headers and thought I would share in case it helps.

Studs 90080-12008 & 90080-12007
You need 16 of the 12008 and 4 of the 12007 if you replace them all.
Nuts 90080-17817

I haven't actually bought them yet, so it might be worth double checking.
