Howdy folks.   Question for those running the Cavalier racks in their rides.   Where can one find the coupler necessary to attach the steering shaft to the rack itself? I can’t seem to locate a replacement and all the yards near me are bare of any 80’s- 90’s Cavaliers and their counterparts.   The shaft out of the rack is a 5/8” double d with a recess for a pinch bolt.  I can find no one who makes a 5/8” u-joint that isn’t splined.
