Back in  in the 90's there was a Z Products company

they were around before the '90's as well..  they offered their Z bed
conversion kits for ''68-'79 baywindow buses too... and splitties..    i used to
have a '72 baywindow with the factory sunroof and the Z products  curtain
kit and Z bed kit.. they even offered a rear mattress ad for the deck  area
over the engine as well.
