Series 88 Roll Cage

[Kelster1055]

Does anyone have any photos or design comments for a rear tub roll cage (safari cage) that will fit under a hardtop and a canvas top?
I'd like one that's connected to the chassis - not just the tub.

Here's a few pics of what I have in mind - but can't find a source for.
