Nice work Felix.

T

and that is how you do that

I can't wait to see this thing! Your project is my number one inspiration for asthetic design....

After fabricating the profile, I cut a separate length to extend to the fenders and then formed some wheel opening flanges. Since the fender was not straight, I had to fill the highs and fillet the lows to match the the gentle "S" curve. I fabricated plastic coated cardboard plugs for the fiberglass intercooler intakes and then bonded them in the rockers.

Awesome work, Felix!
