I finally tracked down a set of rust free unmollested Dodge Demon Doors from April of '72.

I needed a different driver side door (couldn't fix the crash damage on the one I had). So I decided to track down a set with out the heavy crash bar.

I weighed both of my '74 Duster doors (with the crash bar) and both of the Demon (with out the crash bar) on my bath room scale.... in my garage.

First the Duster Doors (with crash bars):
Driver side - 85lbs
Passenger Side - 84lbs

Now the Demon Doors (with OUT crash bars):
Drive side - 68lbs
Passenger side - 69lbs

I went back and weighed all four doors (2 with the crash bar and 2 with out) to varify my readings. No granted this is a bath room scale and isn't exactly a precision piece of equipment.

Both sets of doors were complete with glass (minus the interior panel).

I hope this helps somebody somewhere!
