Installed an eBay front left door seal. Broke some skin under a fingernail. It hurts. I'm surprised how well the seal fit. It's identical to the OEM seal. High quality. It was a single length unlike OEM seals. I hid the split under the door pinch seam cover. The dash and pinch seam are so tight, it took me an hour to install it.

Edit: I'll take side by side pics of both seals to post. Plus a link to the seller. I'll inspect the other three door seals. I'm sure the driver side was the worst.
