Removing rear window; 66 Valiant

Can I, as one person, remove the back window on a 66 Valiant myself? I've got one nearby in a junkyard, but I'd have to pull it out myself. Someone tell me how to do it.

Getting out of a junk yard should be EZ. Take off chrome molding, cut rubber gasket with a box knife. Don't let it fall and break. Maybe put a towel on the package tray area to cushion it. Trim should come off using a screw driver to pry it off.

Not familiar with that early but believe should be very similar.Here is pretty much what I did on 75 Duster. I think my daughter was around to assist, but could have done myself.
Get trim off (With a clip release tool best to not damage it) pull rubber lock strip if it has one. Cut the gasket lip over glass and remove from top and sides. leave bottom part of seal uncut to act like a hinge. Lay a moving blanket across the trunk. Get inside and slowly push one corner till glass moves out from the seal. (this was worst part for me. Did mine in July and it was like an oven inside) Don't get too crazy with it cause bottom might not be holding much and you could launch it if you push to hard. Work it across till top of glass is all free and part of the sides. Go back outside and continue working glass loose. Cut bottom of seal if needed or just pull the whole seal off the flange and leave it on to protect the glass. Do not chip an edge! Back glass should be safety glass that explodes into a million little nuggets. Not laminated like front.

Thanks guys. I will try it myself. Sounds easy enough. No way to save the gasket in case I need it?

Maybe - if it is near perfect and soft, pliable, not too much nasty 'glue'... Certainly people do re-use gaskets, cause not every one is reproduced. Installing glass can have enough difficulties without dealing with old gaskets. But it will save you a Benjamin...
If you want to try - Use a putty knife or similar to loosen the seal from over the glass first instead of cutting lip as said before -then go inside and push glass should start to pull out of seal. If too much glue for glass to release, it's probably not worth risking glass break to save the seal. Can try to work some windex or soapy water in there as lube for the glass to slide out. Don't want to tear the seal. I rounded the corners on a small metal putty knife and fine sanded so no burs scratch glass or cut seals. Also have a set of yellow plastic trim tools from HF that were a great help removing/ installing my glass. I highly recommend NOT using screwdrivers! I even sanded/smoothed the corners off my plastics when seal started to tear stretching over lower corner of my front glass. In or out heat will help. Cold gaskets are not flexible... Good Luck!

One year only window & the seal is not available.
You could consider a sawzall & cut it out.
I did it once on a '66 Valiant convertible, it was a bit less cutting than the rear one you're talking about but I was able to save the seal. It wasn't fun.
But if the seal is bad then just cut the rubber seal with a razor as others have said.

I robbed the reveal moldings and gasket from a 68 notchback in a parts yard years ago. The yard owner said, "If you break that glass you buy it too". I did have a helper. We didn't break the glass. It was hot summer time and the OEM butyl sealant was still somewhat sticky. I used a plastic tool to pull the gasket away from the glass and sprayed armorall like silicone in there from a pump spray bottle. The guys in the cleanup shop called this stuff goats milk. They used it on tires, etc.. Anyway, that kept the sealant from re adhering as we worked all the way around the glass inside and out. No seats in this car so we piled several old tires inside to create backrest/recliners of sorts. Shoes off and 4 sock feet against the upper inside of the glass and slow even push. The upper portion of the gasket wanted to roll out with the glass so I let it. I was spraying the goats milk at that while pushing although most of it was raining back on me LOL. Once the glass was out all the way across the top and part way down both sides, we went out, peeled it the rest of the way out and laid it inside the car on those tires. Good reusable gasket and moldings earned.

Thank you gentlemen. I got the rear glass out today all by myself. I was hoping to save the seal, but after messing with it for over an hour, the corners were still too tight, so I had to cut it. It wasn't long afterwards that the glass just pushed out. Thanks again.

Cutting that seal is a bummer, they are not being reproduced and are very hard to find in any condition! The whole damn assembly is hard to find!!
