Thanks, you guys - you have, as usual, educated me, and given me greater confidence.
My mechanic and I surfed for a suitable piloted reamer. The only one we found we were comfortable with was $155.00 at McMaster Carr, and it didn't seem worth it for something we may never need again.
Dropped the kingpins, bushings, and steering knuckles at a local machine shop I'm confident of. May live to regret not doing it in-house, but life is risk!
Will have them back Thursday - will advise about the quality and cost!
Thanks, all!
