This idea poped into my head to day and I was woundering if it has ever been done. It looks like it would be a simple task. Take the hardtop from a blazer and put it on a suburban. I would think that the glass would be the same for the rear windows and rear side windows. If a person was handy with metal or maybe even just handy with a welder and some bondo. Just adapt in the bed rail and back of the cab. + = Just something to ponder I guess.
