A few years ago I bought a tilt wheel from a co named GM Tilt at that time. After finding the wiring harness was 100% backward, I called him and he said he got most of the columns from other 70,s GM cars like the Olds Omega, Pontiac Ventura, ect. Maybe the camaro linkage straightened but the nova platform did not. After I reversed the wiring plug it worked fine.
