Proper voltage regulator/

[Jim Maxwell]

Well, I must issue a retraction. I blame it on failing eyesight and the fact I lost one of my bifocal contacts. The regulator is not original to CSX 3288, being a C8TF, not available in 1966, I think.
rokndad, I agree with you that the C5TF makes more sense and I think is correct for 55 amp alts. The Shelby American parts book dated 12-23-66 lists the regulator as C5AZ, so I wonder if that is where the C5AF idea came from? I don't have photos of the details of any original unrestored 427s in my files. Can anyone else help out here?

Here are some notes I have:

Parts listings show:

C5AF-10316-A 1965-67 Autolite Voltage Regulator Black/Silver
C5TF-10316-A 1965-67 Autolite Voltage Regulator Black/Silver - with A/C

"C5AF" units were originally intended for use with 38A & 42A alternators while "C5TF" units were for 45A & 55A alternators.

I have C5AF-10316-A Autolite as the correct p/n

I think the above are OEM and the C5AZ were replacement (OTC) parts

Thanks Jim and Ron. So I guess that sort of solves my mystery. I now just have to find a C5TF-10316-A (or C5AZ) regulator rated for 55 amps that has the silver and black cover. So far, I've run into block walls and have seen only the ones with the yellow lettering. Anyone know out there where one of these silver and black beasts might be found?

Found it! Mustang Depot, $29.95. 1965-67 C5TF-10316-A with A/C. This site is great.
