In the 1st quarter of 2017 I enrolled (again) in a "body shop" program at our local community. This time to replace some small areas of rusted sheet metal in my '88 RC. It was such a nice low mileage, original interior, not modified in any way 4wd RC. It was/is the Garnet red pearl coat, very $$$$, and the paint was fading so I decided to go ahead and put a very good paint job on it. Then I decided that since I was going to do all of that. i wud go ahead and replace all of the seals, weather stripping and glass channel runs and anything else that could be replaced, I replaced it, including the windshield. One of the instructors,who is a body shop manager in his day job, advised me not to mess with the vent window rubber seals because they looked good and they were a real booger to install. Me, knowing better, decided that I wanted the perfect, all new looking 1988 RamCharger. Two experienced paint and body shop men worked very hard at installing the vent window gaskets and guess what! I shudda listened. I have air leaks, bad air leaks. It may be the product. I ordered them from a very reputable manufacturer who had a video on youtube as to how to install them. Since I got mine they no longer offer the items for sale and the "how to" has been removed from youtube. I think Steele makes the seals so I may try another set. The RC looks super. Of course I removed all of the trim and am in the process of buffing it and re-installing the polished pieces. Wish I knew how to post a pix of it on the site.
