I have a Torsen Diff from an 05 MSM. It was removed at 48K. Was not abused.
this is just for the diff not the pumpkin/carrier. I know you will need axles from an MSM to use this as they are slighlty larger and have a higher spline count than standard miata axles. I am unsure about the pumpkin/diff carrier and whether it is specific to this diff or if you can put this in a standard pumpkin?
