If your oem lower door seals are still good I suggest keeping them. Aftermarket lower door seals do not fit correctly, the end pads are molded all wrong, and GM has stopped making replacements. Aftermarket roof rail seals fit ok. Worn door hinges will through off the door adjustment and make seals not fit either.
