My steering shaft is missing 3 of the 4 little plastic plug caps where it's designed to collapse There is absolutely no play in the shaft right now, my guess is seized, so not sure it'll perform as designed if I need it to (really bad day). I'm sure with a good whack I could break them loose, clean them up, but then what?? Pretty sure I can't reproduce the designed shear value from the factory. Any idea what I could use for the plastic plugs or some other way to reassemble this shaft?
