Denny- The ball bearings are the oem front wheel bearing. The tapered bearings are the MBS replacements. I got them from Chevs of the 40's and Classic Truck Parts. I don't know if they are still available, since Japan has had an earthquake, tsunami, and nuclear meltdown since I've gotten them.
Ihe MBS are a tighter fit. Some emery clothe to the spindle is necessary. The OEM felt seals won't work with the MBS bearings either. The Timken seal in the picture is a pretty tight fit too. I'm going to eventually order a seal with a slighter larger ID.
