Do you have the vent window out of the door? I have only repaired the vent glass and divider with the door glass and vent window frame out. But your mention of new whiskers leads me to believe your glass and divider are still in the truck. Where specifically are you in the process.
I recall I soaked the vent glass in solvent to soften the tape and used scraper. You can find the tape at your local glass shop and I had them press it in for a few $$. Made process easy and I was certain they would get the tape flush and straight.
