Hey! I just got my 1990 300zx and the weather stripping around the t top and window frame was leaking. So, I purchased the czp replicas and had a professional install them because I do not feel confident in my abilities to put them on correctly. The mechanic said they fit like garbage and are not sealing properly. So, now I do not know what to do. Does anyone know of a better brand to try? Maybe somewhere I could find some OEM or New old stock replacements? Thanks!
