I just bought a 08 burb. I noticed that the upper trim/seal on the outside was missing. The previous owner probably was scrapping off ice and popped it out. I can't find a replacement molding anywhere online. I think rockauto has them but are out of stock.
Anyone have a better source for these parts? It's not leaking yet. I thought about just running a line of black silicone but would rather do it the right way.
