I had the full cage in mine, doorbars, diaganal (non removable), the lot, the one that didnt need the dash cutting to fit.
Fitted quite nicely, just took a LOT off fiddling, dont even try to attempt it without removing almost all of the interior (barring the dash) of youl think it doesnt fit at all, soon as its all gone you realise it fits bloody well.
Sits mega tight to the dash tho so if you ever remove it (mine was welded in, and as you have to weld in proper plates to fit any cage to FIA spec, so unlikey) youd have a mark on the dash where the rollover bars were.
Damn, im having flashbacks of my old 3door Cossie

I miss you baby
