HDK Tubular Coil Over for Stock Steering

Denny, for the part of the pivot that goes throug the K frame I think 1" OD where the taper is now, maybe for 3/4" and the 3/4" OD the rest of the way to the 1/2" threads. I will use 1 1/4" OD 0.125 wall 4130 and insert some 1"OD 0.125 wall 4130 in the larger tube for the small end. Both the 1.25 and 1.00 side of the tube assy will be welded into corresponding size holes on the K frame, with reinforcements where they pass through. I would hone/ream the inside of the tube assy to be sure it was round/right dia. so the pivot would fit tight. May need maybe 1/8 longer on the pivot shaft so the shoulder at the threads was flush with the outer edge of the small side K frame reinforcement, and of course the big side would stick out like it does now, but that would be the reinforcement plate on that end which I would weld to the reinforcement plate before honing. That way the ID wouldn't be changed from welding it to the K frame as the heat would then be on the outside of the reinforcement plate.

I am going to try to rig up a pilot (probably make it from a stock pivot pin) for a hole saw to cut the 1 1/4 hole. I think a step drill could do the 1" hole. I have a scrap K frame here to test this on.
