!2 bolt conversion bearings

[SSDan]

Well...I will be modifying my rear end and removing the c clips for the new Wilwood disk brake setup. The problem is....I'm getting mixed advice about the bearings. I may race the car at the local quarter mile, but I will be cruising mostl of the time!

Global West says go with the ball bearing style bearings. They are used for drag racing, but....Pyle Brothers, that will do the conversion, says the ball bearings will leak after 10,000 or less miles. Pyle Brothers says you need to go with the roller style bearings for cruising and they will not leak like the ball bearings...

Whom do you believe??
