964 rear windows in 87 911 coupe?

[89911]

Do all 964 rear windows come with the 3rd brake light black masking? We are looking to put a 964 rear window in a 911 coupe and already have a high mounted (993 type) 3rd brake light and would like to keep the rear window uniform. Thanks.

Could you give me some detail on the install of the 993 Third Brake Light? I've got an '87 and I am contemplating the install of this.

Cheers,

Chris
