RMNE is looking for some info for brake rigging pins on a PRR class 2D-F31 truck; this is also known as a GSC "BX" truck. We have a PRR print for the truck (C-443570-B, 10-24-49), and the various pins are referenced by a number which corresponds to a "pin chart" (which we do not have).Specifically, pin numbers 2,30, 39, 40, 41 are the sizes called for. We need to know the dimensions of those pins.Anyone out there who might have this info/chart/list? Thanks in advance,Howard P.
