this question has been asked a million times before, but I just wanted confirmation from you guys.. my cougar has a 7.5 rear, I bought a motive gear set and ford racing trac-lok for a mustang 7.5". As long as I remove the cir-clips from my half shafts, this should be a direct swap, correct? since the axles are held in place by the knuckle and the larger axle bolt on the hub. the axles don't have any risk of sliding out. sooo...whats the point of cir-clips?
