I was going through the green K5 the other day (found a bunch of tools the PO left!) and noticed that the top was different than my other one. The green one has the bolts coming through the top and there is an aluminum piece that wraps around the edge of the top and the bed rail. This one seems like it would be a lot easier to remove/replace than my other one, and it has two lights on the driver's side (one fr. one rear) that also have a wiring disconnect (my yellow one has one light with elec. tape to put the wires back together). Is this one a single or double wall? Are the glass and back hatch interchangeable? Can you patch or repair the fiberglass and do it right? (crack on rear corner that has been repaired half-ass by PO) Any info on these tops is appreciated.
