67 gtx rear window installation question

[Dallasdrifts]

Finally found a rear window for the gtx how are they held in? Is it the weather stripping and trim or it it butle tape or silicone?
Thanks in advance

Original was installed with a rubber seal. I would not be surprised that some have been installed with butyl tape and urethane adhesive in more recent times.

Thanks I found the seal online for about 200 all said and done not really sure if there's an advantage to either way
