Steve,
I can take your order no problem. My thoughts on the metal pieces you refer to.... were these the strips of metal used to backup the rivets on the backside of the floor panels? The White/DiaT sets will not have these. The Autocar set will have metal backing strips. Going by the original flooring it seems that White and DiaT simply used a washer to backup the rivet while Autocar had these strips. I should be able to send you a set but need to have at least a couple samples for the convention.
