68' Dart

Now that the body work is done, the tear down begins. I'll be filling all the holes but two in the firewall. I really like the 2" TTI headers, but it is so tight on the passenger side that I cooked the paint on the inner fender. I guess I could go with Schumacher's (will probably choke 50hp-75hp) or use some of the "A" word material between the headers and the fender unless someone has a better idea?
