Tips on stretching the side panels in the back. I have fold/wrinkles.

I feel for you. Not sure what Chrysler was thinking about having the rear glass panel attached blindly to strips before attaching to car.

I guess the installers got really good at it. Mine had 2 installers, one on the left and one on the right. The right hand guy was neat and malicious, left hand guy sloppy cuts, staples all which way.
all you have to do is center it on the rear bow. it works every time if you do that and the top the same way. Also another trick is to put the top on with the front header raised up about 2-3 inches and put on pretty tight, so when you do latch it down for final shaping it is as tight as a drum and look great(and no "pillow" top going down the road). now the sail panels are tricky and require some work, but if you have ever seen a 4 door lincoln convertible done you can appreciate how easy our mopars are. (yeah I helped install a couple of the 4 door lincolns since I work part time learning how to do convertible top installs and they are a pain)
