hey tb, i can't take credit for how i installed it, since the method i got was from info i got here at fabo. i wish i would have took a video of install , i couldn't find one anywhere. when i do my 70 duster i will video the install and post it here. my dads duster windshield gasket had failed (original) from getting old and having a cut , which caused a small leak. i was able to remove his windshield without damage. i don't know if i would ever try to install with an old gasket since i couldn't see getting the glass out without cutting it since it would be dry and old. all i can tell others is a helper really is a must in my eyes and don't be in a hurry.
