Need help on trim rings

I got my Rallye wheel center caps from Layson's a few years back. I chose the 1970 Light Argent vs. the 1971 Dark Argent (personal preference).

They still have them here (I selected 1970 SuperBee as you said big bolt pattern):

I've had mine for about 10 years (about 10K miles), they still look great and the price was comparable.
