74 HEMI Dart Sport

Yep, well aware of that. Dusters vastly outsold Demons so they felt the name and character on fender was steering sales away.
Nice HEMI !! what measurements up and down fore & aft are you using for alignment of motor and trans and are you using stock k member or going with Hemi Denny front suspension set up, drag link to oil pan clearance issues with stock k member, TTI has some measurements on there web site for headers they have which I'm kinda using on mine - 72 Demon.
