I am using Norbtachs web pages to print off truck trailer bodies on cardstock and glueing over blocks of wood to form the trailers. I don't like the look of the cardstock tires. I'm not talented enough to scratch build the tire assemblies. Is there somewhere you can buy 1:87 scale tires and wheels or the whole undercarriage? A Canadian supplier would be handy. This is my first post so I hope it goes okay.
