I had a buddy of mine cruise by my house and take a look at my A833, he told me its in good shape but that we should change the input shaft seals and output shaft seals. So Im trying to find which ones I need? I have the 70+ A833 with that little bar going across the cover plate. It has 23 spline up front and 29 spline rear. anyone know where I can get them or what to look up? Im a little lost.
