Classic Mini lower door sliding window channel MK1 and MK11

The MK1/2 Mini, with sliding door glass, is considered the mother of all classic Minis. The glass slides inside a felt covered dual channel. This channel works great when in good shape but will deteriorate after years of exposure to the sliding motion and the rain and dirt of years of use. Replacing it should be an hour long task that will renew a 'classic' feature of your Mini.
These are the non flexible version that are as close to original as currently available, with stronger reinforced internal wire and holes for drainage and fasteners.
