1/4 glass window channel....

On my search for mk1 doors (3 door) noticed that some had a short window channels. (Between 1/4 glass and winding glass..)

Both my chanels are long. Is it possible to cut them down a few cm before pop rivet at bottom of door, will winder still work and glass stay in place??

I want to fill pop rivet hole at bottom of door, i think that it promotes rot to lower door.   :?

When I restored my GTI I used some doors from an A-Reg Driver 1300. There where lots of detail difference between original GTI doors and the ones from the Driver, you?d think they were from different cars!

I can?t remember now whether I swapped parts between doors or kept the bits with the doors that they came with. I would prefer the long fixing that goes to the bottom of the door, holds the glass better and makes the door slightly stronger.
