Any help appreciated, I have scoured Google with no good results. I'm at my wits end with trying to fit a replacement rear passenger door glass. I have the door panel off, lower window trims and I can drop the glass into the door. I just cannot work out how to get it into both runners. I have tried tilting within the door but cannot get enough rotation. I obviously cannot take off the runner that also holds the rear quarter window. There doesn't appear to be a way to loosen the front runner. I have taken off the internal trim which didn't reveal any 'magic' screws to loosen the fwd runner. I tried to prise off the fwd column outer trim but this appears to be quite fixed in place and didn't want to force too hard.

Thanks in advance.
