If there is anyone who is familar with the body construction of the 1991 to 93 Mazda 323, I have a question about the two mold trims on the roof which are near the doors and runs the length of the roof. Is it easy to remove? Also is it possible that under the trim the join is leaking water into the passenger compartment? I have a leak that I believe is coming from there. I have checked all the rubber weather strips and they are fine. I have also replaced the rear light gaskets. If anyone has any suggestions, I'd appreciate it.
