K-member delima

I've been debating on a tubular k member for my 65 Valiant. I'm not concern about weight, for some reason I really don't feel 10lbs is really gonna kill me on a motor that pushes 550+ with torque to match in a 2800 lb car. I know I want rack and pinion and remove the torsion bars, my issue with stock is clearance. The motor sits below the hood and the inner fenders haven't been mutilated. The motor is a 361bb, built as a mountain motor, high compression, high rpm, all motor, not bottle fed. Exhaust are factory 69 440 magnum manifolds. Steering box is causing a clearance issue, so it was removed, attempted a front steeering retro, and the Ackerman is all messed up. What units have the members used and found to be the best in their opinions. I've looked at HeMI Denny, Alterkation and Magnumforce. Please help.
