Doug's headers not fitting - frustration

I have put a flat washer under the 2 inside/inboard steering box mount bolts, to angle box away from engine, then loosened the 3 bolts holding the steering column base to the floor, to align as nec, - to gain clearance.
I have seen a u-joint replace the coupler, can't remember vehicle.
"Flaming River" comes to mind, not used one myself.
