The 8 1/4 thread

I guess we need to Find the gear size break ( I don't remember) then we will know what you have because we know what won't fit.

Let me research that some as well. Not sure but if your carrier is on the smaller gear size I have a 2:45 ring and pinion I Just took out of my unit when I switched to 3:45s

You could have them if they would work for you. That's if a 2:45 is even acceptable ratio for your wants/needs.
