The alternator is all original, nothing changed or replaced in it. 60k miles in 56 years.

Who sells the D635 and what's the price?

Man, I couldn't tell you, I stole it off of my now not running '66(going through changes) a few months back. If I'm not mistaken, it was on there when I bought it 25 years ago. Sorry bud.

You can find NOS ones on eBay. The cost seems to be between $175 and $400. Lots of them are labeled NOS but are "new old stock" from aftermarket vendors.
I think the NOS usage in this manner is bad advertising.

I had mine rebuilt but an individual who specializes in this service. Did an amazing job and ran them at temperature to confirm everything is correct. I have had zero issues with his rebuilt regulators. I wasn't able to find the vendor quickly but will look it up if anyone is interested. The Delco regulators are also date-coded if that is important to you. The date is why I had mine rebuilt.

MacataQ, now is your chance to upgrade your charging system. Unless you just want to keep things exactly original, you can install an internally regulated alternator.. Minor wiring modifications and you're in business.. How to do this simple procedure is all over the internet, including our own ELECTRICAL forum.

Thank You. Now I really feel Old. LOL
