I just did it on a 66 A body and it was a real challenge! I had to remove the side glass, no big deal there. I left all the window mechanism in the door. Then I removed the side vent window; that was tricky because there were alien key bolts under the weather stripping. All in all getting the vent window out wasnt that bad especially the second time because I forgot a screw. Removing the seal and replacing was a long process and quit hard to get the seal back in. I must have struggled with the seal for a couple of hours. Theres probably some trick to do it but I just heated up the seal in warm water and put some WD40 all over the seal track. I used all kind of tools to push the seal in the grove. I ground down a common screw driver till it was quit rounded so as not to rip the seal. That was the main tool I used. If I can do it Im sure you can. I cant wait to go for a drive in the spring to hear how it sounds.
