I need wide transam style fenders front and rear for my camaro 1970, i'm building a vintage racecar chapparal camaro (replica).
Does anybody know where I can buy'em.

The majority of those cars used a fiberglass flared front fender/airdam assembly.
You can try contacting Herb or Matt Adams -
@ Herb Adams VSE, Monterey, CA 93940, (831) 649-8423. (number if from my card files - hopefully it's still good)
They used to sell fiberglass componenets for Camaro/Firebird TA type set-ups.
I know they still sell suspension parts - maybe they can help.

Is this the type of flare you are looking for?
