    Hi I have a 89 sportster 883 4 speed and was wondering why im told that I cant swap out the tranny with a five speed from a 91 sportster. The five speed has a 90 part number im told. Are the cases differnt. Or are the shafts different sizes,, different distance apart. Just want to have a second opinion. Thanks ORTIGO
