hi jim,
these seals are not the same seals as all that are available. if you were at my shop i can show you in person the differences between the seal brands. if you hold ours against an nos seal they are as good as it gets as far as aftermarket is concerned. the difference is not how soft the seal itself is! its how soft they are where it attaches to the molded blocks at the tops.
as for your doors not shutting when these are installed, there is a reason that is happening and it is not the seals. dimentionally something is off. (as with most broncos it seems) lower quarter in a bit too far, rocker in a bit too far, there are a lot of causes for this. now when you adjust your doors in to match it ends up being too close to the inner rocker for any seal to work! try measuring the door openings on 10 factory broncos and you would be lucky to get the same dimensions top and bottom on 2! i have, as well as many people on here have seen a ton of factory, never touched broncos with the doors sticking out on the lower corners. its not because of the factory seals! its because the gap between the door and the body is not the same all of the way around. due to a panel misalignment.
ive told a lot of people that i cannot "gaurantee" that these seals will be a fix all but they are in fact better where it counts the most. if the body dimensions all check out, these seals are fantastic!
i can say this, we use these as well as selling them and they are the best i have found , if there were better i would stock them. its not all about profit with us, i want to offer only the best products. we have also sold nearly 500 sets of these in the past year and have only had 2 or 3 people say they did not work on their application. thats good odds!
i hope that helps.
thank you,
Nick
