Goodness.. i cant get my windows to roll up evenly. it tilts slightly toward front of car. Also it keeps popping of track on side near quarter window. I have taken everything out, cleaned and put back in tight. ANy advice?

I am wondering if something like https://zcardepot.com/products/window-glass-roller-bumper-guide-240z-260z-280z?_pos=14&_sid=b266dadb1&_ss=r

would help? I dont see this on my 71 model.

There are fairly detailed instructions and examples in the Factory Service Manual regarding the adjustments to the two "rails" you may need to look at to get proper window movement. The  part you mentioned may help you in other ways, but not with the issue you've described above.
