Front wheel bearings? 64mm or 66mm?

[Nobby]

Hi guys im looking to replace my front wheel bearings on my new big block hubs. Now 1 of the hubs is fooked but i want the flange/big block hub so i measured the bearing and its 66mm, but i will be using another hub off another car thats possibly a 64mm bearing will there be any issue running a 66mm bearing on the one side and 64mm on the other? :confused:
