82 xj650 forks with an 80 xs650 wire wheel. What bearings???

[Garlic_Sauce]

I swapped the front end off my 82 xj650 seca to my 80 xs650, the stem and rotors fit on my xs wheel but the stock 17" axle is too big. The xj axle is too small so I need some info on what bearings I need to run in the xs wheel. Also if there's an axle off something else that would fit would be cool too. I checked allballs for specs but couldn't find any inner our outer sizing info. Any help would be great. Thanks.
