First off, I got this car partially disassembled . The back door glass are out and all the trim was off front and rear doors. I now have the trim back on and am trying to put the glass back in. After a short delay today to get 3 staples in my head after running into the corner of the trunk lid I have tried to install the glass with out any luck. They left the channel that the rollers at the back of the glass move up and down in laying in the bottom of the door. The adjuster screws don't appear to have been moved. I have put the channel in first but the angle is wrong to get rollers into channel. Then glass in first sliding the channel over the bottom roller but can't work it up to the top roller. Neither way works . What am I missing?

Thanks,
David
