I picked up two spare sets of spider gears for a 4 spider conversion as I wasn't sure what the OEM gears would look like when I pulled them out. The OEM parts ended up being great, so I didn't use these sets I picked up of spider gears. This is two spider gears to be used with a modified or aftermarket cross shaft (not included) and your original spider gears. I have two sets, so if you're looking for a total of 4 spider gears that would be $500 shipped. Otherwise for two spider gears I'm asking $250 shipped. The price on their website is $230 AUD, which is currently around $162, however shipping to the US after tariffs etc is an additional 230 AUD bringing the total to around $324 USD. These are already in the US with tariffs paid, so you'll be saving over $70 getting them from me than from Neat. Also, they are currently sold out so you can't get them from Neat even if you wanted to. Also the OEM parts are NLA so this is your only option for new parts. If you want these shipped outside US you need to pay any duties or tariffs.
