STEERING SHAFT U JOINT

[73SwungOut]

Howdy howdy everyone. I have a 73 dart swinger (5.2) with PS and I'm switching out my old steering coupler that goes to the gear box. I've seen alot of users mentioning the universal u joints on line. But to my confusion alot are saying the sizes are 5/8 and others are saying 3/4. Would anyone know if this pic I posted is the right fit? I read a thread from a user who said he shaved down the shaft to fit the DD slot but not sure of the diameter..so if I could just get a yes or no on the photo so I can order it ASAP Any help would be so lovely..

Call Borgeson, they should have what you need. They are a sponsor here.

Just know that by replacing the factory coupler with a solid u-joint that you are hard connecting two parts that the factory purposely separated. You may pick up some extra vibration.

I believe the power steering shaft is 3/4-36 spline x 5/8 smooth bore and non power shaft is 3/4-36 spline x 3/4 smooth bore.
Neither are double D.
