Borgeson Steering coupler

Hi Group,
I troubleshot sloppy steering to the Borgeson coupler. The splines were worn down (never seen this before) It is 11/32” 36 spline to the box.
I am wondering if auto part store sourced couplers for the original fit on the Borgeson box.
Anyone with experience with this?
Thanks
Mike

Update:

  1. I cited the wrong measurement. should be 11/16".
  2. OEM shaft is 3/4, so no. not interchangeable.
