fender headers

Wow that's low! Tony, you must be lucky enough to have no speed bumps and cool cops where you live. Have you ever thought about using oval tubes for your exhaust and some "oval Sportsman street" spintech mufflers for some added ground clearance. I've been looking at this for my own big Block Duster that I'm building.
Nice looking Dart.
