64 rambler classic front and rear glass removal?

I've never been a glass guy... I need to get the front and rear glass removed safely from my car. 
The seals need to be replaced and I wouldn't be surprised if I need to do some repair to the flange areas.

not to mention... I need the access for welding up the roll cage

Any tips would be appreciated.  The car still has the bright work around the glass...so I guess step one is figuring out how to remove it

thanks for the tips.  Looks like the front gasket is readily available, and if I'm deciphering correctly, this should work for the rear?

I never had a problem with the replacement rubber (got from www.amcrambler.com -- Peter Stathes). It can be a bear to get in though. The old trick of a string around the top works great. I always put the bottom channel in, so the string would be across the top, down the sides, and in about a foot on each side at the bottom. Seat it in the bottom when you go to put it in, then pull string to pull the lip out and over the flange, evenly up the sides.

Put the rubber on the windshield with a little sealer in the channel the glass goes in.  The "pro" installer I first used didn't do that and the thing leaked -- I had to pull it out a couple months later (thankfully it was new and came out without tearing the rubber!) and install it myself. They didn't use sealer ANYWHERE!!

Once that is done, put the stainless trim in its channel. You can't remove or install the trim once the rubber is in place -- obvious once you remove it.

Now the tricky part. You need to put sealer on the flange (or in the gasket where it mates to the flange), then put the windshield in. Mask off the dash and all metal around the windshield -- you will get sealer on everything when the string pulls out. Have a rag and some paint thinner or alcohol ready to remove excess sealer from gasket/windshield/anything it gets on (like hands!). 2" tape on the posts and headliners is usually enough, just cover the dash.

I put mine in by myself, but it is nice to have a helper who can put pressure n the windshield as you pull the string. Otherwise it's pull a little, get out and push in, etc. until finished. Still shouldn't take too long...

Hmm... let me look at a TSM before I answer.... I was right, they DID use sealer!! Not in the channel for the glass, but on the body. 1963 American TSM (only one I have handy right now)...page 1 of Windshield - Rea Window - Windshield Wiper section, bottom right corner of page just below photo:
"Apply a 1/2" bead of sealer completely around the windshield opening ledge. NOT THE FLANGE."
Capitalized in the TSM, not my emphasis. That would keep water out of the flange at the bottom, and the rubber would push the sealer back to the flange anyway. I've done them like this and still got a little rain seepage at speed (light rain, 55+ mph) around the glass, so I always put a little sealant in the channel.

It's a common misconception that sealer wasn't used with the lip type rubber gaskets. Modern glass companies don't use sealer when they install a windshield in a classic car. Partly because it can leave a mess that has to be carefully cleaned (masking tape and alcohol or paint thinner), partly because most people don't drive their classics in bad weather and would never notice anyway.

My 66 Rambler American with less than 4,000 miles on it undoubtedly has the original windshield and there is grey sealant behind the windshield gasket.  It has the Type 1 windshield with moldings inserted into the gasket.  Joe
