Reviving an old thread with me info.
On my Rotus Eight the clutch slave appears to be a 300ZX part, but I had to drill the mounting holes out to 7/16". Be aware there is a stack of washers underneath for spacers.
The clutch master looks for all the world like Land Cruiser FJ40 part, but alas, the output thread size is different.
A new banjo adapter should fix that.
