split case part numbers

[satchel]

The tcase in my 88 fj62 is being rebuilt and I'm not sure if I'm missing a part or it just isn't on an fj62 but is on a fj60. Does anyone know if this washer is not used on the fj62, or if it is, what the part number is highlighted in the second picture?

Earlier versions of the split case used a washer and a thinner, plain nut. Later versions use a thicker, flanged nut and IIRC the washer and thin nut are not available, so you need to use the flanged nut.
