Did a '69 Z28 without power steering come with a single deep groove pulley? Car has no A/C and smog has been removed. I am removing a cobbled together power steering system in favor of manual steering which I believe the car came with. The car currently has a 2 deep groove pulley and I'm unable to find a single deep groove for it. Concern is whether everything will line up using the existing 2 deep groove pulley.
