Does anybody have a clue what wheels these dog dish fit?

I found these and ASSUMED they were for 15” wheel and to my dismay after purchasing a set or 15x6.5 factory wheels they are way bigger. I’ve seen the on 66/67 chargers and assumed they were normal 15” wheels? Where am I going wrong? Anyone point on a set or a year or body style to find these on?

Thanks,
Jake
