Not quite sure. I dont know much about the 450 and 550 axles. Someone with more experience will hopefully chime in. I didnt think about the fact that you probably have different transmission gearing so i really have no idea what gears you have. Easy way to find out, jack rear end up so 1 tires is off ground, rotate driveline. count how many times you turn your driveline for 1 full rotation of your tire. IE: if you rotate your driveline 4.10 times and your tire rotates 1 complete turn you have 4.10 gears.
Can you post a pic tho in case someone wants to see your setup. I know lots of people do a hub conversion that changes the 8 lug to a 10/12 (not sure which one) lug to run the semi wheels. If the previous owner swapped the axle i wouldn't put swapping the hubs out past him.
