What are these for - '73 disc brake :

I'm pretty sure they are for shooting the pimple faced kid behind the parts counter... I just replaced my driver caliper and wondered about those as well, but with about 30 or so mopar brake jobs under my belt and the fact that I've never seen them before I just threw them away with the box... was anyone else's reman caliper anodized gold? I had to paint it before I put it on.....or get wire wheels :)
