Don,

That's a Billet Specialties part - or a clone thereof. I didn't really want billet, but I came across it for a good price. I had to do quite a bit of grinding for it to fit my fast-burn heads.

Spectre makes some alternator mounts, and they're available in most local part stores or from Summit. Their brackets wouldn't fit my situation, though, because of the headers and the fast-burn aluminum heads on my motor.

If you want an old school look, you could use the Alan Grove driver's side top mount, Part #200L.

Then, there's always 3/16 cold rolled, 3/8" rod, a rod end or two, a saw and a welder. Worked on my big block A-bone.
