Alternator on flathead V-8

Has anyone installed an alternator on their 239 flathead? If so, what type of alternator did you use and where did you get the brackets? I have figured out how to convert to 12v but decided against a 12v generator because of the dim lights at idle, low power, etc...

Thanks

Alternator on flathead V-8

Knucklebuster,
In October I put 5391 miles on my 48 pickup in 18 days. It's a stock setup except converted to 12 Volt neg ground. I'm running 12V field coils in the generator and it performs without a flaw. I can't figure where these guys are coming from complaining of dim lights. Just doesn't happen!
I did a complete rewiring when I rebuilt the truck so my grounds are all tight and other components are new. For what its worth - tim

I installed a GM single wire on my flathead using the mount from Summit (or was it Speedway) - well one of them. Piece of cake and works well.

If you can fabricate brackets and match the pulley to your fan belt, I would say a standard 65-early 80s Ford alternator and external regulator is the way to go. Wires in easily and is simple/cheap to maintain or replace.

Go for it !!
