i need help on changing my rear glass . It looks like sombody sanded it with a da around the sides when they were doing bodywork on the car.how does the frame come off.it looks like it has 2 holes in the corners were the frame meets how does this come apart and can i use temperd glass to replace the oem glass?

 

There are two small screws in the corner and 2 small roll-pins in an angle in the corner basically in the window channel









Carefully soak everything for a few days with PB plaster and then try to take the screws out (mine actually came out easy)
lay the window flat and pour varsol on one side and let it soak for awhile to loose the sealer
Flip and do the other side
Now you need to gently pry the flat aluminum off without breaking or bending.

I took a pair of wood blocks (2"x4" x about 4") and clamped them to the window against the curves side and another set on the other side (against the flat out as far to the end as I could, opposite the other set) but allowing them to slide on the glass (a bit of grease helped)
Put a set of push clamps between the block sets and gently (slowly) applied pressure until the seal let go,
Tap the curved ends sideways with a wooden block (pins are angled)

More varsol into the open gap and then you can start to work your way around by hand.

Strip and polish the frame pieces

The new glass was about $100 from the local autoglass guy, I see the catalog companies are selling them also
It's only a single layer 1/8" thick, strange thing to handle, feels like it's gonna break

Patience letting the sealer loosen is the key

Hi m,
NICE!
I don't think I've ever seen instructions for removing the rear glass!

i had a 3/16" thick plexi-glass replacement made for about $25 by a local plastic shop. it's light weight and, of course, unbreakable. i tried to make it myself, but without a bandsaw the plexiglass would crack from the reciprocal motion of the jigsaw.

 

Thanks Alan, neither had I and thought I might have to make my own replacement so I didn't want to break the original (mine was also hit with a D/A at some point)
Since everything is curved it made it hard to apply any pressure, that's when I got the idea of using the blocks and push clamp.

I had a glass shop make my rear glass and he had to send it out to be tempered.

 

thanks for the pic and info it will help alot

 

I'm changing the glass in my 70 after getting it shot out w a bb. I'm slowly digging the broken glass out with an ice pick.

Two things:

I got my screws out, but how did you get the pins removed?

Do I need to replace the liner on the inside of the frame or just slide the new glass into it?

 

Careful with the plexiglass. It scratches very easily and will eventually cloud up. Ask me how I know!!

 

You can get the roll pins out with a small punch but in reality the frame will flex enough to let it come apart and then pull them with pliers.

The tape from the old window will need to be removed and new tape added. It's the thinner stuff and finding it can be a challenge.

Here's the most overly complicated method I could come up with to replace mine using Urethane

Hmmm??? "Carefully soak everything for a few days with PB plaster and then try to take the screws out"

PB Blaster...

 

Yeah, you strip one of those in that aluminum frame you'll invent new words the lord instantly won't want you using

Repack my glass last year with the correct rubber setting tape strip (1/32" thick and 1.5" wide) and cut them after closing the frame. Maybe it helps outer people.

 

And I can’t think of anything more dangerous on a vehicle! Plexi breaks like plate glass, very dangerous. Polycarbonate, ie. Lexan, at least has better strength, but, A Big BUT, I don’t know if it’s DOT approved. And it still scratches and yellows over time.

The suggestion of having a pattern made and set to be tempered is better. But that may not be done by a DOT approved source.

Here’s a possibility; Auto City Classics https://www.autocityclassic.com/2-do...glass-db1100t/
Green tint, made by a DOT approved manufacturer, and under $100. And, no, I’m not paid for endorsements. As many people I sent there I should get a residual…..
