So I think your idea is to just install a roll bar inside the cab, only attached to the cab, then the seatbelt shoulder straps could attach to that. I think this is what you are referring to.
Damn, great point.... so... maybe i ditch the whole idea of rollcage. I say this now also because that then interferers with my ideas for a boom box behind the seats in the area.... damn, i am learning all kinds of things today.... lol

Or, do a roll-bar so you have anchor points & have your boom-box idea incorporated into the cage structure as part of it's mounting structure. Skip the pass-through idea. Plate & gusset the cab as required for proper roll-bar anchoring.

That combo won't stiffen the chassis (make it better) but it would offer/increase 'roll-over' protection but even then your head can hit the hoop which defeats the purpose. This is why street cars should not have cages.... because you're not wearing an approved helmet on the street like you are @ the track.
