Rear power window adjustment
 

New to me blazer. Rear window was not working, tore it down and the cable was seized and had to replace the regulator rollers. window now works but it out of alignment see picture. It not centered going into the cap. I have adjusted the end tracks as far as they will go. The gate closes and opens very nice and is in perfect alignment with the rear quarters. How to I adjust the window and or regulator?

It looks like you are missing the rubber piece that mounts on the inside of the tail gate
