This is a bundle item. You pay the shipping to me of ten of your cars that I upgrade to Kadee couplers, metal wheelsets and to the NMRA recommended weight. Assumes the trucks are four wheel . The old couplers and wheels could be missing, broken or just an old type. Price includes the parts, labor and shipping back to you.
For this work, I accept cash, MO or Paypal payments.
