I was going to ask what the serial plate is mounted with because mine has screws in it. I am used to seeing rivets holding in the other ones but was unsure since this is my first big bolt. could it be that some one changed the plate at some point, also changing the tire size as well. I found the number off of the rear end it is pn0220 but I can not find where to decode it. Also the trans number is sc192631 and it is a sm420. If you can make anything from those numbers it would really help me. I was looking for a two ton anyway for the extra capacity.
