I need some window alignment advise. I've been building the passenger door on my Aventador and I am really struggling to get the glass to align properly. I'm using oem Aventador glass, seals, and A-pillar track. The remaining parts (regulator, and rear track) are from a Grand Prix. The window curvature is nearly identical. I shortened the regulator tracks, but maintained the curvature.
I had everything working perfectly until I took the door shell off and did some body work on it. After everything was reassembled, I found that the finished door shell sat slightly differently on the door seal. This ultimately resulted in the glass no longer touching the seal. The tracks are not adjustable, so I was forced to move the rear track brackets.
Now, I have the glass realigned with the seal, but no matter what I do, I can't seem to get the tracks/ regulator lined up correctly so the glass can go up and down smoothly. It'll go down properly, but then jam on the way up.
Firstly, does anyone know of any short curved regulators that would work? I don't think they are causing the jamming problem, but it would be nice to have some that don't need to be so radically modified.
Second, does anyone know how to set up the tracks (rear track specifically) so they can be easily adjusted?
Any other alignment advise?
