What wheel bearings do our trucks use?
 

I was wondering if the inners are A-6 and if the spindle will fit an A-2. I know these are the passenger car bearings, and if the spindle will accept the I.D of these, a sleeve could be used to adapt these to car rotors. A buddy of mine just did this to adapt the A-2 bearing to A-body/S-10 rotors for his impala. It works amazing and keeps the track width factory intead of 1" wider like the aftertmarket stuff.
