Hey guys I need to rebuild my differential< rear wheel bearing, carrier and maybe pinon bearings whilst in there!!! Does anyone know the part numbers for these bearings??? My mechanic about _hit when he saw the OGTS pricing for these and said they got to be cheaper than that! His bearing supplier doesn't show a kit for a 1972 Opel GT, but believes he can get the parts if he has the part numbers. Like to be able to do this without disabling the car right now.
