I've got a Dana 70 front end, closed knuckle, with drum brakes and big six bolt pattern. Is there anyone who can tell me if there are parts avaialable to put disc brakes and eight lug locking hubs on this monster? The Dana 70 has 4.88:1 gears, and I have an Eaton HO 72 rear, does anyone know where I can get a 4.88:1 gear for my Eaton? How about a locker? Thanks.
