Well on my homemade vacuformer I can't get anything thick enough to mold right. Thin aint a problem but I wouldn't put my name on it in a dd. Also without a turbo truck for me to test on I'm worried they might catch fire or first good time the underhood temp rises the fenderwell will just reform on top of the tire. Louvers are also a no go, turned out just bad, real bad.Sorry guys I tried. Now I'm gonna go play with making gauge pods for the speaker grill and see if I have any better luck.
