I've been using the two hand close method for over a year now. Owning two bodyshops, I'm accustomed to taking interiors apart. I started pulling the system out of the truck but honestly, other than I can see where it's got some play in the rails (which allows the slide on each side to bow and put the sunroof in a bind) I can't see how to adjust it.
I hadn't thought about taking it to an aftermarket sunroof place but perhaps it may be worth it.
The only way to buy new tracking is to get it with the motor. ($1600 bucks)
**** that, I'll use two hands...
(I'm use to using two hands anyway.... )
If any of ya'll take or have taken it to an aftermarket sunroof place, let me know... I'm curious.
