Heald Hauler Front Wheel Bearing Numbers

I'm working on this Heald Hauler for a customer and need to replace the front wheel bearings. Anybody know the correct bearing numbers so I can order them a head of time ?

In Oklahoma since it's a kit my Heald Super Tryke will be able to get tagged, I have to register it as a kit then tag it as a "low speed vehicle" and a warning sign must be posted labeling it as such. No highway use for sure and on some roads you must maintain 25mph or more but a car going super slow gets a ticket here.
