98 740il windows

I am trying to find and buy door windows. Mine are dbl pane glass with security?
I have called around town and glass company for cars they say they can get them
but cant tell me if dbl or single pane. I have checked e-bay and so on, if you all can help me
I sure would appreciate it. Thanks LTJ

Thickness is the giveaway. Compare your good window with a Toyota. Go on from there. I doubt if you will get an original from any indi supplier.

I found that these windows are dbl pane windows now if I could find if they are with or with out anti theft?
I have called BMW dealers 4 of them Cal., Kansas,CO. and Nebraska 2 of them say I don't have anti theft windows
2 say I do have and 1 is not sure. does anybody know how to tell if they are or if they are not anti theft windows?
Thanks LTJ

What physical feature makes the glass "anti-theft"? Is it a thin wire that will break and sent off the alarm if the window is broken? If so there will be connected wires to the base of the glass in the door. Get to know the differences so YOU can tell THEM which is which. All easy after that.
