Door window glass interchange

[flatspin911]

I have a 72 911 coupe and I changed the driver door window. Now it fits very snugly to the point it barely goes up and down the channel.

Are all coupe window interchangeable?

I see that by PET the part number for 64-67 Left windows are:
901 542 101 20 - clear
901 542 101 30 - green tint

Then from 68 to 84 they part number is:
901 542 101 25 - clear
901 542 101 35 - green tint

Does someone know and can confirm the difference between the 64-67 couple door glass and the 68-84 glass.

I found a window glass from a 70 911 coupe. It is slightly different -- narrower in the middle -- thank the one I had. The 64-67 glass binds in the channel whereas the 70 doesn't. They look very close - even the sekurit part number is the same - but the later one has a DOT number. Live and learn!
