Windshield gasket debate/problem

[AASmedic]

As most of you can probably relate, it is a pain to get a new windshield gasket that fits correctly. I have read many post and threads that speak of the night mares that people have endured to replace a windshield and gasket. Heres my problem.....

I have a 72 K20. My truck has the "shallow" stainless trim around the windshield. I purchased a new gasket and tried to install everything and failed at least 5 times. Upon further investigation I thought I may have the wrong gasket. I went to my local "parts guy" and he said, yes I have the one for the "shallow" trim used on the 71-71 models. I got it home, opened the package and low and behold........its the same as the one I had. It is the Counterpart Automotive gasket. Does anyone know if these are made universally to accept either the shallow or deep trim?
