So I've got to ask this question because I lined up the Box along with some other misc. parts to make this swap on my Diplomat.

The engine is currently out so it's easy to get at everything.

The one thing I've been trying to work through is the use of either the Borgeson coupler, or the Bergman one. However, as I look at the Bergman one I keep on asking myself this question: isn't this just the Mopar fctory unit with the bottom piece having been replaced by the Borgeson 312500 steering coupler welded on?

That 312500 coupler is a '11/16-36 spline x 3/4- smooth' setup.

So provided that I have a welder whom I can trust (and I do, he races on the dirt), why would I even consider buying either Borgeson or Bergman coupler if I already have the 312500 coupler ready to go and it's just a matter of getting it welded on?
