[FC] 65 FC ALternator moutning bracket - cast Al

[BBRT]

Folks,

For '65 FC's: I presume GM used an alternator vice generator? Correct?

If so, I recognize it was externally regulated.

My question is about the cast aluminum mount that provides oil fill tube on 
cars. Did GM produce a casting with the aluminum boss cast like on earlier 
generator-equipped FCs or did they plug it (converting a car mount)?
