67 5460346 master cylinder question
 

I have a 5460346 master cylinder, with the numbers cast upside down. It has no machined area on the front pad for code letter stamping. Above front line port it has YA 3087 stamp. By the front bale cast D 4. The cap has USE DELCO BRAKE FLUID SAE J 1703. Is this correct for a 67 Chevelle.
