No that is definately not the kit to buy especialy at that price, it is the old style with solid brass bushes that will require a reamer as Chris says. The later kits from Poland are about a quarter of the price and seem to be precision made so you do not require reaming. If the king pin is broken then your wheel will fall off so I guess he means worn. Pretty easy to check if you jack up the car and check for movement. If you only need to do one side then get the good side greased up PDQ to keep it in good nick. If you get a kit you will also need a new top metalastic bush as well. I did write a bit about the recon process not so long ago.
