davealden and Fast Fredy,
What did you use to couple the splined shafts to your steering shaft? I've found some steering U-joints on the internet but none of them seem to match the diameters of the shaft on the equinox eps. I measured .720 dia with spline count of around 36 on one end and .650 dia with a spline count of around 24 on the other end. The spline counts may be off, I didn't bother to do a careful count since I couldn't find U-joints of the matching diameters. Maybe I just need to buy 3/4" D-D joints and make them fit (and weld them). Any suggestions? Thanks.
