The seal that goes between the roof and stainless trim is a sponge material that is available for car applications from various vendors. It is very similar to the weatherstripping tape that you would purchase at Home Depot / Lowes for home use. The car application is unique for the width and thickness and is relatively inexpensive. The screws that holds the roof rail stainless trim in place is a very unique phillips head that is relatively difficult to come by. A couple of the vendors stock them. They have a very shallow head with a broad shoulder if that makes sense. For the roof rail weatherstrip, I strongly suggest to our customers to try to reuse their originals or purchase the Steele variety as opposed to the Metro piece. The Steele piece is almost double the price, but at least the door glass will roll up into the channel properly. For the weatherstrip that goes on the front edge of the door glass, I strongly suggest using the factory Mopar pieces. Depending upon who you buy them from, the original weatherstripping will be $20 to $50 more for a pair verses the reproductions. Hopefully this will give you guys some insight into those areas.
