I haven't really looked at it, but if the window regulator for the rear quarter is anything like the LeBaron's, it is a beast to take out. It was not designed for serviceability. The company I worked for back then produced them in one of our sister plants...I had wanted to change the windows on my Lebaron, and received free test glass from that plant, but when I started the replacement process, I gave up... That is also why you see a lot of old Lebaron's with the "Shark Fins"...the motors on the regulator would quit due to the poor water management...
