Standard guage 400E

The cat knocked my 400E off the mantle last week! (Yeah, i know, what was it doing on the mantle?–and the cat got the heave-ho!)
Any way most of it survived the fall, except for the steam chests casting, which holds the drive rods, and cross heads on both sides! WOE!
Would there be any chance of finding that part? Or, is there somebody who could repair it? I haven’t taken it apart yet, but it looks like the center pin or bolt that holds it in place has broken off!
