I recall they're available for the previous Ranger and for certain Nissans, including the 350Z / 370Z and the Navara... as here:

Still 50k pesos, will probably be around 60k after shipping and tax... but it'll be the last time you ever replace a flywheel.

Expect much more vibration, but the SMF will last much longer than a DMF.
