I know. "fat" chance of that happening...(Not you, Travis)

I agree with Mark; welded tabs with the proper fasteners should be acceptable. If NHRA still has a concern, then use and aviation high temperature lock washer such as the NAS1061, and use a high temperature aviation lock nut such as the MS21046 which is good to 800°F.
