Found them on the JCW website, but no photo of the specific fenders, only a later application.

In addition, the application listed is from 1960 to 1972 C/K Fleetsides. I thought the 1967-72 Fleetside beds differed from the earlier beds?

I could not find a website for Ricka for more info, nor a phone number.

I did see their dual wheel conversion adaptors. Boy those look cheesy. I hope their fenders are a better design and quality.
