Old 2006 article - there are lots of ghastly stories out there on them.
This one is a little newer and has good links to even more at the end:

I have a friend near Ft Walton Beach FL that has the complete molds for the flared CMC California Speedster version. We've talked of buying 50 gallon drum of resin and "flashing" some bodies. Unfortunately fiberglass and resin are not cheap. I'm not sure it would be profitable unless we moved South of the Border. Buying 50 gallons reduces cost but it does have a shelf life. I'm sure the EPA would come knocking too. I'd love to make a trailer like the red one that shows up at Carlisle.
