This what we mean by loose glass in the doors of a 69 mustang.
How to adjust door glass 1970 mustang.
Keep in mind that a little adjustment at each point makes a huge difference so adjust in small increments.
It is easier to install then the factory 69 bond in.
Loosen it and adjust the height of the rear of the glass so that the window will close evenly across the top and re tihten.
Replace the glue in glass with 70 type bolt in glass.
This is because someone rebonded the glass into the brackets and scraped out the old bonding.
My window wont slide easy i.
Took out the regulater and it seems to work good.
Hey guys have a 69 mustang with the 70 bolt in glass.
Just those 3 bolts and 1 nut do all the adjustments you need.
This bolt is in an oblong hole in the door.
The best way to solve the problem is to do exactly what ford did for 1970.
Are you trying to adjust the window fitment.
My drivers side window has been really hard to turn up and down.
If the door is off just a tiny bit up or down at the rear you can lift or push down on the rear edge.
The regulator where it mounts to the window bracket on the left side in the pic has a slot that allows the window to be adjusted forward or rearward.
First try to lift up using your hands.
Is the back edge sticking out too much or in too much.
For you guys that are familiar with the door window adjustment.
If this does not move it enough use a floor jack but put a 2x4 between the jack and your door edge to spread the load.
I found this pic on line that may help explain my problem.
Did you ever think of going with the 1970 mustang bolt in setup.
You can do it several ways.
Mine are all new 70 glas.
Usually the door will be low and not high in the rear.
