My cousin had this problem, which he solved it by epoxying small correctly size/length bolts to the ring.
He ground the heads of the bolts down so that they were thin enough to still have some strength but not thick enough to obstruct anything when bolted together with the hood.
The remaining thin hex gave a good footprint for the epoxy to hold. They were able to be tightened up to the regular torque specs after the epoxy cured.
Thanks, I was considering something like that. I tried a machine shop but they said the ring was too thin to drip and tap. I will try what you suggested. Thanks again!
I drilled mine all the way through and tapped the ring then used 3M panel bond on the holes and threaded studs in. I let it set up overnight then came back and ground the extra stud and a poxy off body work and painted it and you can't see where they were.
