Borgeson requires you to drill all the way thru one wall of the the d shaft and tightened hard against the opposite. Think they got sued and now they provide a 1.5 " all thread allen head with locking nut and explicit diagrams and instructions. The surface of the hollow D shaft was soft but halfway in it went to rockwell off scale. Ruined 3 new tin drill in floor drill press despite low speed and coolant. Heaven help the guy with only a hand drill and one bit. Sent them a nasty note and promised i would post it here and on Amazon for not replying.

Borgeson also requires you to grind a flat spot of the steering box stub for the set screw. Mine fit fine with 4" of collapsible length. that part of install was easy. The really bad part is grinding about 0.10 off the diameter of the steering column hub. Royal PITA for a $200 item so heads up. Pics next time after i recover from the install. Even the titanium rods and 29 screws in my rebuilt right arm are complaining.
