1970 Z28 steering gearbox

I have a 1970 Z28 with the Sawginaw 5691676/ (4 bolt unit but only use's 3 bolts) steering gearbox on it. According to spec data the optional power steering on the 1970 Zs came as a variable ratio at 14.3-10.9:1 for 2.3 turns lock to lock. I sent my gearbox to Lee power steering in Valencia, Ca for a complete rebuild and to verify the ratio. I was notified that my gearbox was not rebuildable and the they could build me a new 3 bolt gearbox that would be a straight 12-1 ratio. Does anyone know if this sounds right or what the difference is.

Re: 1970 Z28 steering gearbox

Straight 12.7 to 1 is fine. I like it better than variable ratio. We used it on our second gen Camaro. But they must install the stiffer IROC type valving or it will be too sensitive.

Check my web page for First Gen Camaro suspension info:
