5 door 6Ns stripped out or caged?

Evening all,

I've been searching around on here for track 6Ns with cages or even show cages but can't find anything for the 5 door models. Does anyone have a picture of a 5 door with a roll cage in or even just with the rear seats removed? Been toying with the ideal of a 6N as a weekend toy and there's several 5 doors going dirt cheap locally and thought it'd be worth a punt.

Is there any difference in rigidity or weight in the 3 door vs 5 door 6Ns? I know a few of the VWM mk3 golfs were made it 5 door but I think this is just to do with ease of replacing a door rather than a 1/4 panel, presume Polo's the same.

Taa
