I've see regular caps on El Camino's, and they never look very good. Saw this a few weeks ago at the "Back to the Bricks" show in Flint, MI. Never seen anything like it, was very impressed. Camper was fairly origanal, just cleaned up. Elky was nicley restored. Definity built for that application, fit like a glove!
Yes, I cross posted to Classic Motorsports in my excitment.
