I've r&r'd multiple front and rear glass out of necessity, aka, no one knows what they're doing anymore and I'm broke.
I was amazed at how easy it was, a little nerve racking, but that is required to do it correctly.
On my 62 Dart, the fsm stated to put the windshield on top first, impossible.
I tried it bottom first, had it in within 20 minutes.
Plastic scrapers, cord for inside the rubber, something that won't fray and will stretch, spray bottle with soapy water.
I made a few boring videos of it if needed.
I'll be doing my 67 Barracuda in a few, with 68 stuff.
