You are on the right track because you are going over everything. We are not suggesting you are not careful, just good to go down the list again. BTW: The door is supposed to be slightly lifted by the striker as it engages the striker. I just asked about the rubber because it can be put on wrong even with all the retainer pins snapped in place. The strikers could be put on the wrong side and up side down. Also are you sure the door strips are NOT side specific? I think they have to be? If they are preshaped to the contour of the doors and the cross section of the rubber has to be a certain way, they must be side specific. I have done TF doors and now I can't remember, just thinking out loud. I know you said you copied the old door seals. WARNING. the seals CAN BE put on wrong and look right and will not seal as yours are doing. It is possible the old one's were on wrong or you just flipped it. This is most likely your problem. You need to go on the internet on the Brothers Truck Parts website. They have a complete installation of 55-59 door seals showing how it can be put on wrong so you can see and compare.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
