Hi all! I have a 66 amazon 4 door that i have owned and been working on for almost 7 years. I recently upgraded the seatbelts to modern aftermarket ones (now that i have a kiddo, for the rear too) and the next area of safety concern for me is the steering column. The steering box has leaked for years, and i'd love to upgrade to the later model (6 collapsible shaft and box for safety. Am i correct that the later box is necessary for the later column? Anyone have the used rig for sale? Or has anyone used aftermarket parts to make this safety upgrade? Funny the things you start caring more about when you become a parent..
