so has any one worked on an amc 20 rear before?i believe i just blew my pinion gear so is this a complicated job or something that is terribly hard?does anyone know of a website where it gets into a lot of detail.i pulled my cover as i noticed that it had a hole blew in it from chunks of my pinion getting thrown around.i am a bit scared to just start taking it apart i have hand tools and a little vehicle smarts but this i think is pushing it any help is appreciated!:welder :beer
