I was able to find prices as low as $75 to change the seal. However (1) no guarantee that the glass will not be broken (2) what if there is rust that needs to be treated in the channel.

For these reasons, I have sucessfully done 2 rear windows and a windshield myself (well- family project), as well as 2 Triumphs and a VW.

And I use only the cheapest non-OEM seals. No problems yet. I don't know where that OEM seal bunk started- probably with the glass pros who would rather pay (or have YOU pay) more to save 15 minutes on the job and go on to rob somebody else. The OEM seals MAY fit a bit better in the top corners, but that's not where the water comes in.

Don't use silicone on the glass to metal seal (OK on glass to rubber seal , though) It contains acetic acid which is not metal-friendly
