Installed new Doug's headers on my 72 340 demon and see that they are touching the torsion bar on the driver's side and touching the bell housing on the passenger side. Could this be a problem? Do I "dimple" them in with a hammer? Hate the thought of beating on new ceramic coated headers but...

Greetings; I have a 72 Demon with a 340. I just installed the long tube headers from Dougs and when I went to install the Z-bar that I purchased from Mancini racing I found that it will not work. I have included a couple of photos to help with you seeing what I am dealing with. The first one is...

Greetings; Looking for information on what kind of clutch fan came on the 1972 340 Demons? Non A/C car. Did they come with the thermal control drive or did they come with the torque control drive? Looks like there were two different size of thermal drives one is 7 1/4" diameter and another one...

Couple of questions here. First question is will I have to remove the tie rods from my 72 Demon to install my new long tube Doug's headers? I am hoping that I can just lay them inside, tie them in place and lower the motor back in? The engine is currently out of the car, I have manual steering...

Hello out there; Can anyone tell me what other models if any will match up with my 1972 Demon rear bumper? Do the Plymouth Dusters use the same ones? Thanks you
