Hi from Australia. I am glad to find a group interested in Rovers. As a teenager, I can remember one of the teachers at school had a light blue P6 V8 Rover and remember it being a cool car. Many years later I satisfied my curiosity and bought a P6 3500 on a whim. I love it, it is a 1976 Paprika 3500 which purrs along beautifully for a 34 yo car. I recently needed to repair the rear window the window dropped. I found the channel rail that held the glass in place had disintegrated with rust. I was fortunate enough to locate another one in good condition but when I check the other doors, was disappointed to find the all the other three have rusted channels to varying degrees. Can anyone tell me if this is a common problem with the P6? Is there a suitable replacement available to replace these?
