I am changing to a 12 volt system on my flatheat 239 engine for a 1948 f6 .I have seem many difrent precasted brackets for the alternator. I was wondering if any one has used one and can recommend where to get one that will work.also i looking for a one wire altenator any recomendation. thanks for the help

 

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.

 

Look@ this item-#140213213645-on Ebay right now.Yours for only $119.00-OUCH!you can also make your own for about 20.00.Do a search of the archives.Steve.

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

 

Sorry,I missed the fact that is was a flatty.As my kids say,I'm a big bag of Duh!

 

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.

 

Only if you don't count tensioning those damn belts!! That is the worst part!

 

Awww come on Ross, a little swearing never hurt any truck belt!
