Aloha Fellow Wrench Turners! I’d like to know what these seals are called, officially by GM. They are at the bottom of all 4 doors and mine need to be replaced as they are turning sticky. The residue is like a sticky tar and hard as the dickens to get off. I’m interested in finding out what they’re called, can I get them from anywhere besides the dealer, and the securing clips. Appreciate any help you folks can provide. Mahalo in advance. Aloha!!
