McMaster Carr is a good place, as is almost any good auto parts store that caters to heavy duty applications (tractors, trucks, etc) as most cars today don't have fittings.
I've found though that the fittings on the front wheels aren't standard (or at least available anywhere). The other fittings I pulled out I just tapped back into place.
I pulled out fittings from the plastic deck wheels, one of the steering spindles and one of the front wheels. They are just lame little press fit fittings, rather than proper threaded fittings.
I'm sure eventually I'll get some epoxy and glue 'em all in. It's the only gripe I've had so far about my 2544. Otherwise I love it.
