Years ago I bought ones similar to whats mentioned in above post, fitted them in my XR3i, Jetta CLi and Jetta VR6. They worked a treat and could roll up/down as required. I bought them locally at that time when spare/accessory shops were better than these days - just not sure if it was Fleishmans or Something like that, may even have been a midas. There were two or three sizes in widths so just be aware if ordering on-line etc.
