ok I'll see how much and what type I really need to get(for the ugly blue car in the background) had already bought the 5/8th seal and it kicks the door out a bit on the lower bottom side of the door about 1/8 of an inch . I've had it on the car for a month now and it seals nice but has a little too much seal pressure. If that doesn't bother you much. then you can get the cheaper 5/8th inch stuff. I want the next size down to bring my doors back into alignment, so I'll be getting some of the 1/2 and 3/8 to test my self. I put the original stuff back on and the door closes fine and aligns good. put the new 5/8 inch stuff on and it kicks the door out on the bottom edge no matter what you do. I've even tweeked the door on the bottom side but the seal still kicks it out.
