The assy. order should go as follows, in order from the engine side. (Still can't find that parts diagram I came across.) My pic (sunl) has the first two out of order, which is how it came apart. After studying it and the Carter (which had them the other way) I'm pretty sure the carter or is correct and is listed below.
1: Thick spacer with the slightly smaller inside step, step side faces reverse gearbox.
2: Narrower spacer with wide ID. The ID matches the step and "locates" the spacer in relation to the axle center.
3. inner gearbox case.
4. (Inside of case) thin steel shim against inside case side.
5. Primary "sun" gearshaft.
6. Outside half of the gearbox.
7. Lock nut. I found a "vibration proof" nut on BD for 4.95. My carter had a castle nut/cotter pin, the Sunl has a worn out nylock nut.
