I'm trying to find out which bearings size are used in the Backdraft 8E. I'm planning on changing them all to "Avid RC".
So far I found those:
BS903-014(Front/Rear Knuckles // Outside x 4)
BS903-016(Front/Rear Knuckles // Inside x 4)
BS903-086(Front/Rear diffs x 4)
BS903-087 (Center/Front/Rear diffs x 6)
