Bisquik1959 Posted March 17, 2021 Share Posted March 17, 2021 Done. Both doors still close hard, but at least do close. Based on witness marks the strikers had been tightened up previously (probably to deal with the wasted old seals). But now they're a lot looser than the marks... and the doors don't line up with the body lines at all. Hopefully with time they'll break in. Ugh. I did my door and window seals about a month ago. I still need to slam the doors to get them to shut. Hopefully they will compress down to normal soon. Sounds like thats just part of all new seals.

Gary Lewis Posted March 17, 2021 Share Posted March 17, 2021 Just tested it... much easier with the windows rolled down! Yep. With everything sealed you are trying to compress the air in the cab when the windows are up. I think the 87 and later trucks had a vent to make shutting the door easier.

reamer Posted March 17, 2021 Share Posted March 17, 2021 Just tested it... much easier with the windows rolled down! Roll down the window and close the doors, if it is easier your battling the "Air Cushion" created in the cab, This is why on newer trucks, they have flapper vents on the back cabin wall. they "fart" when the door closes, letting the air pressure out. I need to crack a window open for the doors to close. Link to comment Share on other sites More sharing options...

Big Blue is sealed so well that opening the kick panel vents or turning the HVAC system to something like Vent doesn't do much. But if you crack a window, open a wing vent, or crack open the sliding back window you get a lot of air and your ears tell you the pressure dropped. And closing the doors takes a firm hand - unless a window is open. There is a huge difference. Link to comment Share on other sites More sharing options...

When I did my son's 83 Mustang Convertible, I put a sleeve in the bulb where the ends meet to keep them together. Couldn't hardly shut the door. So I put some vent holes in the rubber like the stock seals had. At least on my 78 they did. Shut a lot better. Link to comment Share on other sites More sharing options...

kramttocs Posted March 23, 2021 Share Posted March 23, 2021 This is an original factory seal. Note the holes. The reproductions do not have these. The Precision brand kit I ordered has them. They are the opposite factory so they aren't seen unless you look for them. Can't say the entire Precision kit is great but have no complaints on the door seals and would recommend them without hesitation. Link to comment Share on other sites More sharing options...
