Yes that's right. 500A is 440 in modern dimensions - most 20 inch wheels are 406 these days. Tyres and tubes are readily available in 440 and you'd find spokes but I reckon new rims might be a lot harder to come by. Steer clear of rusty chromed rims I'd suggest.
Would 451 do the job, or some other similar BMX size not suffice. Or would there be a mudguard issue?
