steering coupler replacement (how to)

I just called Steer & Gear who recently rebuilt my gear box and talked to Tom who's an A-body guy. He said guys come to him with this steering coupler conversion to U-joint question all the time. Mainly guys stuffing big blocks in the A-bodies with little header room. He suggested the Borgeson over the Flaming River because of the shaft size and obvious cost difference. Apparently he hasn't had anyone come back to him with complaints so I'm going with it.

Just ordered mine from Summit - $71+$9 shipping = $80
