I used the aftermarket OEM style replacement weatherstrip from MSA... alot cheaper than OEM. Initially it was hard as **** to close the doors, but after a couple weeks in the Texas scorching sun and a few open and closes.. they work very nicely. No slamming at all. Alot of problem with door slamming is miss alignment, worn hinges, striker plates, etc. A couple hrs adjusting will save ya weeks of headaches. But then again I have the later style latches... 78
