The ofna diff cups use the 8mm ball end for the bones and will work with your center bones
The distance between bearings is 29mm, but the bearing seat is not bumped out like yours so that’s probably the difference.
The main measurement are:
End of cup to cup – 78.75mm
Center of cup to cup – 69mm
Height from chassis deck to top of uprights (without top plate) – 51mm, spur protrudes lower than chassis deck so the deck needs a relief (If your deck isn’t cut you would need to cut it or shim up the CD for clearance)
Center of spur measured from inside edge of rear upright- 6.75mm
Then you would need to measure the spread pattern of the uprights, the ofna has a wider spread in the front compared to the rear.
Gear ratio: If the stock spur is 60 and clutch bell 14 you would need the 12T clutch bell to get the closest ratio with the 51T spur.
