All the gaskets you need for the Toyota diffs and transfer case. There are 2 washers that look the same, those are for the transfer case. Then you have 3 washers that look the same - 2 are for the rear diff and 1 is for the front. The copper one is also for the front diff.
Please order two additional aluminum gaskets for the transmission if you're changing the oil in all 4 gear boxes in one day. Much cheaper to buy in a kit than individually.
In case you struggle to keep up with Toyota changing part numbers all the time, with different gasket sizes and styles out there, I thought this photo might help, also in case you're looking to see if OEM replacement gaskets would fit. Part numbers are per Amazon product description.
