Ok, so after some searching it looks like our birds are indeed 63.90mm
Does anyone know of a source to get some hubcentric rims that aren't plastic (63.9 -> 73.1 mm) ? If not i'm going to have to go w/ the plastic / polycarbon one's for now 'cause they're only $15 shipped and i'm not sure where to get some custom made cheap.
