Same goes for the pilot bushing (which they also replaced during both of the repair attempts) and the flywheel (which they replaced the last time). The pressure plate and friction disc are the only parts I can find in that area that have different part numbers starting in 2018.

As far as installing the older OEM clutch, Nissan previously told me it's not compatible with the newer car. No idea why that would be, but I can ask again. Otherwise I'll see if I can get them to pay for an aftermarket clutch rather than just replacing the CSC again...
