I need to remove glass from a 73 Roadrunner - I bought the tool withe the 90 degree blade and cable/handle ----- any tips before we start ?

Yeah - for fifty bucks or so, have it done by a pro ...........

If you plan on putting in new rubber, no tools are needed. Just a utility knife to cut the rubber on the outside of the window. Then remove the window and what is left of the inside rubber gasket.

It is tough. Since they are basiclly glued in (butyl), so going to a pro maybe the way to go. Although you can get a new one installed for aprox $250.00 (sometimes alot less), so there is a savings to get it out yourself. Alot of them ending up cracking when you try to remove (even by pros), so good luck.

Thanks ............... you say the kit is NOT guitar string, but can you use guitar string and 2) how do you get it started ?

In my experience as a full time bodyman, the glass I broke while removing usually did so because I rushed it.........I'd be pushing the glass out before it was cut all the way, and CRACK........so GO SLOW! The brass wire is the cats ass, I wish they had it 20 years ago........anyway, start wherever you can push a sharp putty knife or equivalent through, so you can snake the brass wire through. Cut about a 3' piece of wire, wrap each end with some sort of handle (I have used anything from wheel weights to screwdrivers) then saw back and forth. Try to angle away from the edge of the glass whenever possible. It isn't rocket science, but did I mention to TAKE YOUR TIME??!! LOL!

As others have mentioned, just take your time with the brass wire.

Thanks all - still haven't heard a response regarding guitar string or equivalent ?

Why not use the right wire and leave the guitar wires to the guitarists?
You could use it as well as piano wire but why would you? I am guessing you have some lying around. Try it, but the big thing as stated is take your time, windshields break easy. I have broken a few and learned it is much easier to be patient, as mentioned. Good luck.

It is easy to do.

The braided wire is better but I have used guitar strings, welding wire and hardware store steel wire. I have wrapped them around screwdrivers and wrenchs as handles but that kit above is the best and can be had for about $15 in many places.

They all work but the braided wire is best. As Challenger1 said it is strong and FLEXIBLE.

Here are some more tips.

I have found if you take a razor knife and trim as much of the sealant away from the glass & window channel as possible it is easier. The more sealant you have to cut through the harder it is to cut.

Cold glass breaks faster than hot glass. Do it inside or on a warm day if possible.

Never push on the glass to try to break it loose. If it seems to be sticking cut it again.

If you put it in crooked cut it out and start again. DO NOT THINK IT CAN JUST POP OUT AND RESEAT IT.

No wire cuts Urethane glue easily enough.

Use butyl or rubber gaskets on old school glass like ours. Urethane breaks down in sunlight. That is why all modern glass has black edges.

If you can find it use glass & Pinchweld primer for Butyl tape. It used to be common but not so much anymore.

Take your time.
