Power window stops

[RBCarCollection]

Here at the shop we have a 1970 Challenger with power windows. All the windows except for the passenger would go up and down. the passenger wouldn't go up all the way and stop 1-2" before the roof line. No big deal, car didn't have any stops in the door left so we took the entire glass and everything out and replaced it with a rebuild kit. now the window will not go up past 2". everything is greased. even tried it without the window attached and it dead stops at the same place. took the regulator out, took out the motor. manually moved the regulator past the point. put everything back together and back on the car. window can go up to the top but when it hits the same exact spot, it dead stops and can't go down anymore. If anyone has had this problem please let me know how to remedy this

Parallelism. Manual or Power windows work when the is Parallelism set.

I would have to say it's binding up.

Parallelism and Primary Seal
(1) Raise window completely.
(2) Loosen screw at belt on upper end of front
track.
(3) Align and set front edge of glass to “A” pillar
and top edge to roof rail weatherstrip creating a
parallelism with weatherstrip locating bead.
(4) Secure upper
In-Out and Secondary Seal
port.
(5) Loosen bottom screws on front track lower sup-
(6) Loosen bottom screw on rear track support.
Push front track lower support. Outboard for inboard
contact at weatherstrip. Allow rear track to create it’s
own plane, parallel to front track.
(7) Secure previously loosened front track lower
support screws.
(8) Secure rear track lower support screws.
(9) Secure front track lower support screws.
If additional alignment to ”A” pillar or roof rail is
necessary, adjust regulator idler arm pivot
rail is
necessary, adjust regulator idler arm pivot bracket
up or down as required and secure.
(10) Secure regulator arm pivot guide to panel. ////////The long and short of this is.! Door hinges good? door gap aliened to quarter panel. and 1/4 window up and back, not to hit door glass on closing! can fine tune rear later. have track loose at all points, Not falling apart! move forward and up to seal. until satisfied. Idea is to have the 2 vertical track parallel when done and leaning in or out the same. bottom track adjustment when moved have a lager range and effect of movement top not as much. You have to study the components to know what each and ever function
