Topic: '65 45A alternator part number

[CobraSpeeD]

What is the part # for a 1965 45A alternator that would have been installed in a car with a C5TF-10316-A voltage regulator?

I'm trying to determine the correct alternator and voltage regulator for a '65 GT convertible w/ Power Top & PS, without AC. Non HiPo.

Indications point to the voltage regulator being a C5TF-10316-A (black/yellow letters). AMK products along with other sites show that voltage regulator for use with a 45A and 55A alternator. I feel its safe to rule out the 55A alternator being correct.

Using Bob Mannel's book (page K-2) and the web extensively I can't find any reference for a 45A alternator used in 1965 with a small block. It appears the C5TF-10300-B 42A would be the correct alternator.

Any insight on the correct voltage reg/alternator combo (with part numbers) appreciated.

42amp alt typically had a companion regulator with a silver stamp I believe.
