steering coupling??????

If the column has been collapsed, can it still be used? Can it be rebuilt? I bought it from a member here and he said it came out if a 70 duster. I had an original post about the manual column being too short. Redfish said sometimes when the column is removed the shaft has to be pulled down. I tried pulling on it by hand but it didn't budge. It still had pin on the end of the shaft that the shoes sit on. I tapped on that lightly with a hammer on each side and it moved. I may have chose the wrong word "collapsed" to describe it. The coupling came with the manual steering box I bought. The coupling being mounted to the steering box is no problem. I wish I could add photos to help but my phone doesn't allow me to!!!!! Thanks again:)
