Instead of parroting 18 year old flawed arguments about smaller gears, here's some useful info:
The rear output seal to the driveshaft is larger than the common S13/S14 seal. Vendors told me it was a JDM part that would have to come in from Japan.
Turns out the FRS/BRZ output seal is exactly the same size and readily available at your favorite parts stores/websites.
The shifter housing gasket is still a JDM only part, so waiting on that thing.
Also, the aluminum drain/fill washers can use Toyota part as well: 90430-A0003
