When I did mine, I was told to just cut the rubber and buy a new gasket. I had a good used gasket but bought a new one anyway, and boy am I glad I did. It was so much easier working with new pliable rubber when getting that big puppy back in. Compared to the one I thought was a good used one, I can see that the used one was going to be a bear to work with. Bought a new lockstrip too, and glad I did that too. Contact Deuchmann Automotive. He sells everything for at least $10.00 less than everybody else. Good luck with the window, Geof
