I have a 82 pace car. Is there any easier way to change the outside door window sealing strip other than taking the window glass out.

 

remove the door panel back off the inner window adjusters there's 2 remove the screws in ones in the middle are hard to get too I used a bit in a pair of vice grips to loosen them 2 , if you need new triangles it would be best to do them at the same time since your already in there.
