70 Formula 535

[Alponcho]

I need to decide what to do about a roll bar as soon as possible. The car will be street driven primarily, but with 750-800 ft lbs of torque and sticky 335s I've been told I'll need some sort of roll bar or cage to stiffen things up. I'm thinking about getting a DSE 4-point bar (since it's readily available and fits well) and welding in some really low door bars to make it an unobtrusive 6 point. Is this feasible? Are there better options? Will this limit my options for seats?
