Hi Rick,
If you need bearings for the front wheels, the Filling Station and probably other vendors carry them.
I don't have info about the rear axle bearings, but I did replace the felt outer bearing seals on my '28 Canopy Express with neoprene seals to prevent the bearing grease from getting into the brake area. I found a receipt for the neoprene outer rear axle seals that I believe I bought for Justin (see link below) from Bearing Engineering in San Leandro. The item description on the receipt says 32X58X8, which I think is the seal's size. It fit right into the recess where the felt seal had been with no modification necessary. ;-) I took the old seal, its housing, and an axle into the bearing shop and they measured it all and gave me what I needed.
Is there something wrong with your current axle bearings? I would think that you could take them to any good bearing house and they could match you up with new ones that would fit.
Ever onward, Dean
