Doing a Ken Davis Air Conditioner into my coupe. What is the alternator I should get to do the conversion from 6Volt to 12Volt? Where to buy it?

There are lots of places to get a Delco alternator. I use Nurex brcause they are new not rebuilt and have been trouble free for me.

For ease, ANY model A parts vendor can help you.

OR, you can roll your own mount, and purchase a mini alternator (Denso) on eBay, for less than $50 new. Just make sure you get one with a pulley that works for you. These are 55 amp, neg ground, very small and work well. Search for "mini alternator, one wire". I have installed several of these, with no issues, though I did have to put the pulley in the lathe and widen it for one tractor I did, and you may need to do this on the model A as well.

Pulley is hard to find.Upgrade your water pump bearing if your running a stock one.Belts don't have to be fiddle string tight,just enough to handle the load,industrial "B" belts have better 'grip' than automotive belts,they dont last as long but they are easier on bearings.

For my most recent AC project, I purchased one from Snyder's. Their 60 amp is about perfect if you also plan to use Halogen headlights.
Ken Davis also sells them. He could ship it with the kit.

Snyder's part number: A-10001-A12

Nurex as someone previously suggested is also a good source.

Good Day!

As long as you are getting your A/C from Ken Davis, just have him throw one of his alternators in the box. The A/C brackets accomodate an alternator just fine.

Got Alt from NAPA and installed it. Had a bear of a time getting the belt on but once on it is pretty loose so I will have to tighten it. It is a cogged belt over a 2 inch pulley I put on the alt. (Then I read that should stick with the new as the redo's might be not so swift. Oh well, it was fairly inexpensive.)

I got mine from rockauto https://www.rockauto.com/en/catalog/...generator,2412
Pure Energy model 7127SW3 fairly cheap. A lot better than 200 bucks and works just fine. I used metal from spring shackles for the bracket with the appropriate bolts. The smaller alternators do look nice and may have to do one in the future.

I use my local Starter - Alternator shop (Hawkins Starter Alternator, Tyler Texas. ) He puts the small dia. 5/8" wide belt pulley on it for me. Cost about $80 if I 'member right. Ask for a GM one wire.

Jeez, I paid more than that in '83 for an alt for my Chevette at a FLAPS!
