Any insight/ lessons learned, etc installing power steering in a 30s fat fender? Specifically, I'm shopping for a power steering gear box. What are your thoughts on stop to stop ratios? I'm seeing 3, 3 1/2, 4, 4 1/2 rotations stop to stop. I'm leaning towards the 3 1/2 variety used in the early 70s Camaro, Chevelle, etc. Just thought I'd grab some input before hitting the "BUY" button. Thanks ya'll.
