Is the rear 1/4 glass the same for a 71-72 RR and Charger? B-pillars are different, but are the glass, regulators, and mechanicals the same ? This is for the hardtop not coupe.

I don't see how they could be. The RR has a much larger opening then the charger.

I dont know about the 71-72 but I think it is the glass is the same from 71-74. The 73-74 are the same and those I KNOW WILL interchange with regulators and windows and all. I took out the crap opera windows and the fiberglass plugs on my 73 charger SE and took the windows and regs out of a 74 satellite and even the bolt holes and alignment spaces were there. Bolted right up easy as pie and even used the same bolt markings on the regs and the window alignment was very close!

Glass and reguators are the same for Charger and Plymouth for each year. 71. 72. 73-4.
