NAC VW Eurovan Camper top question

[Tony Hoffman]

I'm working on a 1995 Eurovan with a camper top that doesn't seem to
be working correctly. It takes two of us to lift it, and it doesn't
stay up unless we prop it up with 2X4's. Anyone on the list have
experience with these? BTW, it's the top that lifts from right behind
the drivers head, as opposed to the one that goes up from the
windshield back.
