I have been lugging around an old tilt wheel from a 70s? van for a few decades and am finally modifying it to fit into my 55 Chevy. I made some spiffy cuts and welds and it’s looking good. I’m running a modified 605 steering box. The new issue, is I can’t seem to locate a universal or rag joint to couple the two together. If I’m measuring and counting correctly, the column shaft is 3/4”-36 spline and the 605 is (I believe metric?) and measures about 11/16”- 30 spline. Anyone have a lead? Either a universal or rag joint will work.
