Rear window Gasket replacement

[85Ram50]

Rick I appreciate the advice but I already have a new one from Steele Rubber. $93 I watched their video on YT "How to replace back window glass seal with a cord" That is why I am going to try it.
I called Steele Rubber this morning and explained my confusion about the instructions differing from the video. According to Mike the video and you are correct and I do not need to use the bedding compound or sealer. Apparently these are stock instructions the dealer "PCP Wholesale, Solon OH" put in the package. He assured me the seal would "rope in" and seal fine on the Ram 50. One thing the instructions do say to do and I don't recall from the video is to use soapy water in the groove the glass sits in so that it can move and seat as you install it.
I won't be doing it this weekend as it is raining. On to the other money pit truck EGR code
I'm in contact with Mike he's selling door scrapes $65 shipped and he says they don't shrink or curl in the sun. It is difficult to make contact if you don't text, I don't, but he does check his email every few days.
Thanks for that link.
