U-joint vs pot coupler

Hi All,

I have a '67 Dart and I'm about to rebuild my steering column. I had already rebuilt the pot coupler, but my steering column lower bearing was pretty worn out when I got the car, the retainer spring ('67 had this) between the retention collar and the lower bearing finally broke and the bearing popped out of the bushing, so I'll just rebuild the whole column while I have it out. It's like the only thing I haven't rebuilt/refurbished on the whole car.

Question: Borgeson U-joint or pot coupler? I have a Borgeson steering box (waaay better than the factory slop box) and so if I'm pulling out my column to rebuild it, it would be a great time to install a U joint. I realize there are two camps on this. The pot coupler is supposed to be ideal as it allows for movement along the axis of the column due to flex in the K-frame/steering system. I have gusseted my K-frame, added a FirmFeel bearing sector kit to support the steering as well. Those steps took a lot of play out of my steering, but I assume there is still at least some flex.

Any experiences anyone can share about installing a U-joint vs the pot coupler would be great. Good, bad, pitfalls? Installing the U-joint is a one-way street, as I have to cut the column shaft.
