Brad, you would think that about making a cylinder head!
We're not all tool and die guys, ya know....
with milling machines.......
lathes......
I hear what your saying but you could make that with a disc grinder and a electric drill.
If the threads are stripped what about welding a nut on the backside. Then run a tap through after welding.?
cwestra if you get me a paper/cardboard template of what you need I'll make you one?
I did something very similar with the bottom door hinge on my 55 Belair.
