Yours looks to be in better condition than many others I see. What did you try to clean it with ? I've read Easy Off oven cleaner is good for that. A good cleaning and fresh paint will make it look new.
All the texture is gone since I mistakenly scraped it off at the suggestion of a TC member. I believe that texture is lightly sprayed on before painting. Karl responded that he may have one. He will check and get back to me.
The texture is molded into the plastic and I can see it along the bottom. If you used something like lacquer thinner to clean, it would soften the plastic and allow it to come off with a scrapper. Bummer....
I may have one from an El Camino Karl, Randy and I parted out a number of years ago, but I will have to dig when I get back from AZ next week. I know I have the vent assemblies, but I don't recall if the panels were good and were kept.
Have a good time in AZ. Should be a little cooler than now. Karl wasn’t able to find one. He was going to do some more digging. Appreciate you taking time to look. They came blue, appeared gold underneath.
