Sorry not to answer sooner, haven't been on the site for a few days... I did this mod to my 65 Cuda years ago (see link below). The coupler and shaft used to be offered by Flaming River, PN1505M, but is apparently discontinued. It's a length of D shaft with a machined cup on one end. The cup is unsplined and sized for a slip fit over the steering shaft in the column. The articulated coupling is splined for the manual steering box input shaft and the other end mates to the D shaft. I used this to connect my power steering column to my replacement manual steering box. I wanted the joint hidden inside the column's tube so I removed the steering shaft from the column, cut it to length, slid the shaft into the cup and solidly welded the two together then reassembled. I've put the bug in John's ear to start making these but he acts like he's buisy or sumthin! :poke: Just kiddin John...
