door weatherstrip help

I feel your pain. I bought a complete set from dixie restorations and had the same damn problem. Of course I had to trim them to fit for length. Called Dixie and they would not take them back after cutting them. Some members said you had to let them form for awhile but after three months my doors had gaps at the bottom almost 1" wide and the doors had to really be slammed hard to close. I ended up getting the replacement seal for a dodge truck from Rockauto for alot less. Not as nice as the oem but worked. I still had to cut the bottom of the seal in half to get it to close and gap properly.
