Anybody know the application for a 528 CCW Point Cam Plate?

I have a 528 CCW plate and don't wanna throw it out if it's something cool or rare. It could be for a 72' six cylinder station wagon for all I know. I am going to replace it with a 532 CCW. Just wanna make sure it isn't something I should hang on to, or sell and maybe get a few bucks.........Danny

The cam plates were used on many applications. The same cam plate is used on a 307 and a L79 - go figure.
I do not know the usage for the 528 plate.
