77 Rallye rim center cap

This is my first posting! It's good to be here. I've got a 70 Newport that I just picked up a set of 77 Rallye wheels for. Good condition with nice trim rings and center caps. But they only came with three center caps, any ideas where I can find one? The wheels came off a 77 Monaco.
