Roll down rear window roll down or no?

[Fredb_]

When I acquired my 32 Coupe project I wasn’t sure if I was going to have the rear glass sealed into the body or roll down as original. This is a modified vehicle and not stock however it’s not chopped and I’m using original door hardware. I’m now trying to decide if I want to go ahead and get the parts for the roll down rear window since the box that holds it appears to be complete and stock. Any comments on roll down rear window as opposed to sealed in glass on a 32 Coupe?
