I used a tilt unit from a 1973 Pont. Ventura. Nova would be the same I guess, it fit perfect in my 29 Roadster as far as length, had a column shift and ign.switch which really makes the elect. hookups a breeze. I'm running a vega box w/ cross steer. Two U joints 1" 36 spline on the column with 3/4 DD to the Vega box. Just like it was born there. I got the joints from Southern Rods.
