It looks like you may need a Heim bearing support installed in between the upper and lower universals.

I used a mixture on Borgeson and Woodward steering parts on mine. Woodward has wider selection in spline sizes and will mix / match either side of a universal to to what ever you want (spline, DD, etc...) at no extra charge.
