does anybody know of a company that sells 4.10's (the "a" part number not the ones made my motive gear), an one piece drive shaft, and the install kit with a new pinion gear. any help would be helpful
The "A" gears have the last character of the part number as an "A". I believe I read they have the Ford Logo stamped on the back somewhere. I also think they come with a crush sleeve where the Motive gears do not. If you have the box, just look at the part number.
