Alternator number ID help

Need some help with vehicle application for the following alternator:

1100704 37A
8L 12V NEG

I'm guessing Dec 1968 for 1969 model year something ??

Thanks,

[Mr. T]

1100704 - 1969 (350) Firebird, 37 AMP
Casting date/8L - Nov of 1968, 12V

Thanks Tony.

Another alternator question. On 1970 alternators, is the plating on the fan/pulley assembly dull or shiny zinc?
