67 brake booster question

[1967 4K]

Was the 8515 power disc brake booster a 67 Camaro only piece or was that number used on other GM cars? I’m looking at Jose’s black car as reference, there’s an 82 number also. Is that a date number?

Best regards,

Also used on early 68 Camaros. I’m not sure if it was used on other models. Here’s some info from CRG.

9078 was the later booster. I have one looking to trade for an 8515 in the wanted section
