Art,
Here is a link to the place where I bought the alternator.
AlternatorParts.com
If you scroll down about 2/3 of the page, you will find a list of alternators for Fords with external regulators. I bought the 105 amp model, which is Part # F1-55-C-105.
I'll see if I can post a picture tonight.
BTW, swapping the old for the new was a breeze.
Because it is so tight in the engine compartment, I'm always a little concerned about how things will fit, but the new alternator fit perfectly.
Al,
Thanks for the link. I need all the help I can get.
Fortunately, the charging system seems to be working fine now, but I'm sure I'll run into a similar problem on one of my vehicles in the future.
