The column side of the intermediate shaft has a coupler for a 1"dd shaft (which the squarebody trucks have at the end of their columns). So somehow I had to get from 3/4"dd to 1"dd. Too bad nobody makes a bushing to do this... Ah but gm does! And it comes in a long enough piece that you can get 3 or 4 bushings from it.

The hardest part of this is melting out the plastic and driving the solid shaft out of the hollow shaft.
