I'm going to be changing my '52 f3 to a 12v system soon. You'll have to let us know how difficult/easy it was.

They aren't cast, they are fab'd out of two steel plates. I got mine off eBay from Certified Electric. I am beginning to believe a brace back to the intake manifold from the rear of the alternator would be a good idea. Certified sells a turnkey mount/alternator too.

i bought a change over kit from summit to convert my gm alt. to a one wire setup. I have a 351c and used the stock alt. bracket. So far so good.

Flatheads are completely different, and while you can make your own, the slingshot for mounting the alternator is usually only about $35. I wouldn't even consider making my own for that much. It need to fit the front of the intake tightly.

I changed my '50 over useing a bracket like the one Abuq f1 used. It cost me 65.00 at little dearborn in St. Paul Mn. It worked good I used a 3 wire GM altenator with a harness from Summit that has a Diode in it to keep the current from running backwards. The harness was 18.00

That's the slingshot "style" I got from Chuck at Chucks Trucks. 1-wire 12V works Great! Bolts right up to the 239. Hmmm, maybe a 45 second install.
