steering coupler

Hey guys, I'm seeking some advice about the steering coupler. I just rebuilt the front suspension on my 74 duster. I relaxed everything with moog parts. I got the PST 1.03 bars and the Bilstien shocks. I also welded up the k member and had it powder coated. I decided at that time I would replace the steering box. I just replaced it with a rebuild one from the local parts supplier. Right now, I have everything back together except for the steering coupler to the steering box. I can't get this thing back on. I have tried completely removing the steering column and moving it around to get the right angle and I still can't get it. The coupler is about the only thing I haven't replaced on the car so I was considering replacing it. I have noticed in some other threads some guys are mentioning using a borgenson u joint. Does anyone know the correct part to use. I looked on the borgenson website and it only shows an adapter for their steering box. Thanks in advance!
