Quarter window seal install 73 Road Runner?

Could someone please describe how to replace the quarter window seals on a 1973 Road Runner? This is the seal that runs along the chrome trim. Can this be perfomed with the window in place?

If they are the same as my charger then they just slide in the track with some lubrication and then hook on the tab at the bottom. I believe the oem ones seem to fit better then some of the reproductions. I did them on the car IIRC.

Yours has the fixed rear windows? On my satellite they roll down so access is good. If yours are fixed you will want to pull them.

Yeah my Road Runners are fixed. My Satellite is the roll down.
I was hoping that I could take off the upper jamb rubber and "slide" the rubbers to remove and reinstall. Hopefully it's easy. I don't feel like removing the interior panels and taking the window out, and probably wise to do it right the firsttime.
Thanks all
