Replacing Door Weather Stripping And Trunk Seal On A 1967 Ford Mustang Fastback GT – San Diego, Ca

      I just finished replacing some weather stripping seals on a 1967 Mustang Fastback GT. The door seals were never re-installed after it was painted, and have been missing for years. The customer said there was wind noise coming from the doors, but he did not know the door seals were missing. It’s not uncommon to mistake the upper roof rail seal as a door seals. Also, he found a puddle of water sitting on top of the spare tire cover in his trunk from the last time it rained. I started off with replacing the door seals.

      I recommended that the customer order the door seals from Steele Rubber Products.  I have had problems with the rubber being way too dense on the last three door seal installs. The manufacturer that I was originally getting them from changed something in the rubber, and made it difficult to close the doors.  After installing the seals, the door would become very difficult to close about 4 inches away. As a result, I would have to slam the door fairly hard to get them to close. This not good for the door latches, or for the customer for that matter. I’ve tried to trim the seal almost in half, and left the doors closed for a few days. It only helped a little. I’ve heard from Hotrod owners that Steele Rubber Products are made out of a soft spongy rubber. Some of them are dealing with tighter body gaps due to the thick fiberglass, so they need a softer rubber material. I tried their product on this install, and the results were great. The doors closed effortlessly. Now off to the leaking trunk.

      I’m sure many Classic Mustang owners have complained about a leaky trunk. This is due to either the rear window or the trunk seal.  The first place I look is at the wheel wells in the trunk. If it is the rear window seal, you should see dried up drip marks running down the wheel wells. Also, I look to see if there are grove marks in the trunk seal. If there are none or missing sections, then it is not sealing out the water. Of course, if either of the seals are dry rotted or cracked, then those are reason alone to replace them. I have also seen the trunk seals installed on the trunk opening, and not the trunk lid. Those will never seal right. This particular Mustang had sections with no grove marks on the seal, and was not glued to some parts of the trunk lid. After replacing the trunk seal, I check that there were grove marks from the back to the bottom edges of the seal. Everything checked out perfect, so no more towels stuffed in the trunk. Replacing seals on your Mustang does not have to messy when done right. This is from using to much adhesive, or not using the right procedure. One tube of adhesive will last me five cars. If it’s time for some fresh weather stripping seals on your Mustang, please give me a call at 619-929-8506, or email me at david@classicrestogarage.com. Happy Cruising!
