Are you trying to adjust the window fitment.

How to adjust door glass 1970 mustang.

This what we mean by loose glass in the doors of a 69 mustang. Keep in mind that a little adjustment at each point makes a huge difference so adjust in small increments. 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. This bolt is in an oblong hole in the door.

Did you ever think of going with the 1970 mustang bolt in setup. Hey guys have a 69 mustang with the 70 bolt in glass. This is because someone rebonded the glass into the brackets and scraped out the old bonding. 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.

My window wont slide easy i. Replace the glue in glass with 70 type bolt in glass. Is the back edge sticking out too much or in too much. For you guys that are familiar with the door window adjustment.

The old bonding is the alignment. Jack it up a little at a time it is easier to lift a little more than it is to lower it to the right heigth if you go too far. Mine are all new 70 glas. 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.

Usually the door will be low and not high in the rear. Just those 3 bolts and 1 nut do all the adjustments you need. The best way to solve the problem is to do exactly what ford did for 1970. Took out the regulater and it seems to work good.

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. You can do it several ways. It is easier to install then the factory 69 bond in. It turns slightly hard one way which i think is where the spring tension is and easy the other way.
