I am trying to source brake shoes for a 20" car wheel. The cars involved are former 10 ton side dump ore car frames that have been rebuilt as open passenger cars. The brake shoes are very similar in pattern to those pictured on the SPCRR NARF truck rebuild page (see link). I am trying to find out if these are a stock item out there or if we need to get some cast. Any and all help is appreciated. Michael Seitz Missoula MT http://www.spcrr.org/NARFGrantWheels.html
