Gotta agree with the Bad Karma M8!!

As I said Im prob gonna pay some one credible to weld solid panels into mine!!

Any way!! If you do want to go through with it, you can cut any size opening you want really!
:neutral:
The glass is flat therefore you only need to make a template of the opening and take it and a sample of the rubber to a reputable Glass Merchant, Like Myself, and with all the right info we can order the Glass for you in clear or tinted Toughened Safety Glass!!

The Important thing to know is that most auto rubbers take 6mm thick glass, so this is the thickness you will most probably need to order. You also need to make sure that you ask for an AUTO GLASS Stamp on each piece. There are two stamp options! One is for window use, the other for Motor Vehicle Glass. Even though the process for toughening the glass is the same, the Stamp is crucial when it comes time for your Rego!! You can also state where you want the stamp on each window so they are all facing the same way!!

I suggest going this way as you will have New Glass in your van! Im sure it would be near Impossible to find original windows without Scratches on them!!

Hope this helps!!
