Hi all, I'm ditching the rack/pinion steering and installing a steering box off a Super Duty, so I'm fabbing up a custom steering shaft. The input on the steering box is a 36 spline with a flat spot (it's not round). I think just a normal 36 spline U Joint should work. My real issue is connecting to the output of the upper steering column. It's not splined. It looks like it's just a...square. Who sells the U-Joints that can make the a shaft with the square on the top, and the 36 spline on the bottom?

 

I can't imagine why you'd be doing this, but I'd guess you'd have to search out a custom adapter to go from a square to the 36-spline. Jegs.com has a selection of different steering universal joints/couplers you might search through to see if one already exists. Or you might be able to buy two U-joints and swap parts from each to make what you need.

 

I'm doing a Dana 60 swap, that's why I have to go with a steering box setup.

 

FWIW: That flat spot you mention is a "key".

 

Thank you, good to know
