To help you if I can , when installing the rear glass on 67 Gtx used the rope trick , probably 3/16” soft and my wife to assist! It’s not difficult just be careful,especially if the car is freshly painted, I used the caulk in tube , don’t accurately remember , but will look for tube , no urethane on rubber gaskets that’s for new cars best I remember, I used a hand spray bottle and soapy water to lube up and caulked glass groove in rubber after it had been in sun three hours to soften and caulk rubber to channel ! Don’t think that it’s not going to be a mess , cause it is ! Follow the instructions in the FSM ,they knew what they were doing, modern glass guys are like modern upholstery people most are to young to have a clue ! Only old guys can usually do these types of installs and know what you want ! Probably not remembered everything but maybe this will give you some insight ! Not rocket science! If I can help further PM me I’ll always do what I can for guys on our site ! JC
Some things are best left to pros
