This bus had no windows in it so I pulled the ones out of my other bus which is now my parts bus and put them into the Westy.I had to do some work to the Passenger rear window frame so it was the last one to go in.I used the old seals at the time cause I'm replacing them all anyways. The Driver's rear one went in like butter with the tool in the last pic. I borrowed it from work and have not been able to find one anywhere. If you ever find one and have a vehicle with the rubber window seals buy it.You won't be sorry.
