The stock b body power steering couple allows for some fore-and-aft (in and out) play when the car goes over bumps etc...

If I'm reading this right, the Borgeson website lists a u-joint coupler to use when replacing the stock power steering gearbox with a borgeson box.

Does the u-joint replace the stock coupler?

How does the u-joint coupler allow for fore-and-aft play
I can see how it works when the shaft angle is not straight
in alignment with the steering gear. Does it also allow for
fore-and-aft???

Steering gear gurus's please chime in!!
