Since I already had an M10 hole I was nervous about tapping it again. I did tap it 7/16-20 and then had a machine shop take a 7/16-20 bolt, drill a hole down the very center of the bolt and then tap that hole to M8-1.25. I coated the bolt with some high temperature exhaust repair putty (not JB weld beacuse that stuff can get soft at high temperature) and installed the bolt. Then I cut the remainder of the bolt that was sticking out off with a dremel tool flush so the bolt is flush with the head. Then I installed an original M8-1.25 stud in the 7/16-20 bolt.
Hopefully this works for the rest of the season or maybe longer. Hank Scott helped me out again with this suggestion of getting a 7/16-20 bolt, drilling/tapping it, and using it as an insert of sorts for the original M8 fastener. Thanks to Hank!
