Perfect, get these ones!
Perfect fit and replacement for my 2001 Silverado. I had water that was leaking in around the old ones because they were all old and dry rotted. These solve that issue perfect and were so easy to install. It only took me about 1 to 2 minutes each side once I got the old one out. I do have some whistling inside of the truck, however I don’t think that’s related to these. I think that is my door seals since the truck is so old.
