IMHO... if you have the option to get a clutch type (top row except for 2nd from left) you would be better off as the clutches can be easily replaced. all the rest are "cone" type and while they can be rebuilt, require machining.
Regardless of the center section my understanding is that the thrust button or lack thereof needs to match the axle bearings being used.
megavitesare you planning on changing out the rear axle bearings and to which type OE or Green?
My understanding is that the thrust button doesn't allow the axels to seat properly when using green bearings hence the need to remove it when using green bearings. Perhaps I don't understand the issue correctly? (not flaming anyone I just want to be clear on the issue)
