Glad you like them, I think they are the best also over the glue in style. The easiest method to install them is using a rubber mallet to tap on the seal to install it, using the rubber mallet gets them to conform best to the mitered upper corner and fully seats it on the door cab seal lip. You should also cut a angle notch on either end where they meet under the door sill plates so that the cuts form a inverted /\ shape this allow air to expell from the rubber bulb seal as the door closes ( this allows the doors to close much easier than if you butt the 2 ends tightly together and doing it under the center of the door sill plates hides the cuts ) and it also allows any water that gets into the cab to drain out.
For those that order our complete cab rubber kits we offer the option in the cart to upgrade from the glue on door seals to our push on version.
In years past we intially tried using the late model truck door seals such as 88-98 or 82-93 S10 but we found the bulb seal was almost 3/16" thicker than the stock seals which mean't door adjustment & latch adjustment to get them to close well using those styles, about 3 years ago though we got with our manufacturer and came up with a similar seal as the 88-98 trucks and 82-93 S10 seals that is only apprtox. 1/32"-1/16" thicker than the stock glue on seals and since then you no longer have a problem using alot of effort to close the door fully and it eliminated the need to adjust the doors to reduce the effort involved in closing the doors.
