Mine is a 92, not the same.
But when refinishing the door I thought real hard about making the bottom panel glass, like the top.
The newer boats have this and I like the look. May still do it.
I also replaced the rollers with Delrin blocks, and cut each side a different depth for the groove.
Works great, door slides almost too easy.
