I have a 7/16 14 hole in the front of my cylinder head (1974 CJ5 w a 304 V8) that I need to screw a 3/8 16 bolt into. It will get torqued to abt 25lbs. The bolt goes through a bracket that holds the alternator on. It then goes through the top hole in the alternator.

The don’t make an adapter, coupling nut reducer or a step stud that will work from my research. A 7/16 male to 3/8 female adapter would be perfect if one exists! Or even a 7/16 to 3/8 step stud....

I cannot just put a 7/16 14 bolt into it due to the bolt length being 7 inches and needing to be a socket cap and not hex. There isn’t room for a hex head with the blades on the alternator. I might do a 7/16 to 7/16 stud and then use coupling nut(s). This would require drilling out the bracket and hole on the alternator.

I could drill/ tap the hole but that is a last resort.

Any thoughts?
