There are big and small bearings within the 8". Usually the 4 lug have the small and the 5 lug have the big.
There are only 2 sizes of 8", tiny bearing(4 lug, pinto, bobcat, M2, etc) and small bearing(5 lug). The small 8" bearings are the same as the "mustang" 9" rears. the 9" on the other hand offers 4 or 5 different bearings. Somewhere on the 'net there is a chart that shows the differences, but I can't seem to find it.
