79 300SD door window seals replacement
 

I could use some advice on this. I have looked for a DIY for replacing door window seals but can't find anything, even on similar models. I wouldn't think it was too difficult, but the last person to do it on this car only did the front passenger window, and it still leaks into the doors interior. Making sure that the interior of this car stays dry is my number one priority, as I am sure many of you have watched these cars fall prey to rust. This benz lives on the Oregon Coast. I've watched these cars fall to pieces from the rain and salt here. Any advice would be helpful. Thanks very much!
