I have a truck topper (Hop Cap brand), that has the typical rear window
that lifts up (above the truck's tailgate), and stays up by those small
shock absorber looking things on each side.

The frame of this window is aluminum. The window material is a tinted
plexiglass. Yesterday I had some boards on the back and the window fell
(those shock absorber things are weak). The plexiglass hit a board and a
piece of the plexiglass broke and fell out.

I'm going to price a new piece of plexiglass. It wont be tinted, but
that's ok. But I'll have to get it professionally cut because it has
round corners. But if the plexiglass is costly, I may try to just glue
that cracked piece back using epoxy. (unless there's a better glue for
plexiglass).

Either way, I want to take the whole window off the topper so I can work
on this on my workbench, rather than trying to do it in a vertical
position, on the truck. (not to mention that it's cold outdoors).

I see there's a clip on each of those shock absorbers, but I can not see
how the hinge holds it in place. The hinge is NOT screwed on, it's part
of the assembly. Looking at it from the side, it's sort of like a round
sleeve inside a larger round sleeve with a slot in it.

I thought that maybe it would slide out sideways (toward the right or
left of the truck), but that dont appear to be the case. (I did not yet
remove the shock absorber things). I'm wondering if it needs to go
straight up, pointing toward the sky..... (just a guess).
So, I thought I'd ask on here before I try anymore. Its probably simple,
but first I need to know the trick.

Has anyone on here done this?

Thanks
As for cutting the plexi - I used Lexan, but I transfered the pattern
to my lexan, cut it slightly large, then finished the edge to shape
and size with my belt sander. I tried ny block plane first and did
some roughing with it, but found the sande much faster and more easily
controlled.
