Parts are still available Dave. Any reputable spare parts place like Burson's or Repco should be able to help. Rares have king pin sets but are only available .010 thou oversize. I got tie rod ends, idler arm, upper and lower inner pivots, upper and lower outer pivots from Burson's for my daughters EK last year, If you have any problems give us a call and I'll see what i can do.
