I am having my steering box rebuilt. While it is out of the car I checked my rag joint and no surprise it is pretty rough. The other coupler (highlighted in attached) just up from the rag joint is also in disrepair. Any suggestions on whether to try and replace the rubber in the rag joint (only able to find a Dorman Help replacement part number 31002) and rebuild the coupler or go to some other design? I have heard of U joint style replacements or even something about going to a 1974 style which I have no idea what that looks like. Thanks!
