How thick is the urethane(?) sealing material between the rear window and the window channel. I have to reinstall the window and I forgot which thickness I should get.

Car is a 71 malibu coupe with no vinyl top.

I've used the 5/16" butyl caulk on the rear window of my 69 with excellent results, available at local parts store for around 10 bucks.
