mk2 lemons

I recently picked up a mk3 diff but after looking at it saw there was quite a bit different was trying to figure out if you can swap the internals into a mk2 4.10 case or if there is some kit I can get to just put the mk3 rear end in anything is appreciated thx

Hello Everyone, I just bought an '84 Celica Supra that a friend and I are going to turn into a 24 Hours of LeMons race car. This is an endurance race for cars that are bought and prepared for less than $500. Things like the rollcage, race seat, harness, and brakes don't count against the $500...
