Stock Rally Wheel/After Market Center Caps?

[kombreeze]

On my last truck I had stock rally wheels on a custom 64 fleetside black cherry pearl paint job with a very subtle but clean pinstripe. With that alone it was a head turner and won quite a few car shows. Now that I'm restoring a 68 I wanted to know if anyone knows of after market center caps. They are good looking with a beaty ring and wide tire (275/60/15). I actually have clean center caps with the puter colored bowties. What can I do to have the bowtie blue or are ther after market adapters to make a smoothie look. There are so many of these rims being used on our trucks I only wonder if there are such a thing. Wheel Vintiques is only a couple of lights away but there has to be something for our wheels.
