Great looking car! Does it have the original fuel pump? If so, is it natural or painted engine color?
The shifter handle in the car is the wrong one. It should have a "T" handle. They are pretty cheaply made and break easily. I think repops are available.
As far as the tail panel is concerned...ALL 73-74 Challengers had the argent tail panel with black organisol around the tail light lenses. 72 is the ONLY year that is different. In 72, the standard Challenger received the argent tail panel just like ALL 73-74's. The 72 Rallye Challengers got the black tail panels with argent around the tail light lenses.
The fuel pump had to be changed, and it was not painted.
Thanks for the update on the tail panel. The information I got from the Chrysler Historical people had to do with the 1974 Challenger only.
The shifter has been a subject that has been brought up to me before. A Chrysler parts manager I know at a local dealership has a 74 Cuda and it like mine does not have the T hand shifter.
I think to change from a T shift handle to the round knob style shifter, you'd not only have to change to handle, but would also have to change the whole shifter assembly. The booklet I'm looking at while I type this note shows the round button shifter knob, and I got the booklet directly from Chrysler. The booklet is a black and white manual called "1974 Challenger illustrated facts and feature manual".
