When I did mine I’m sure Mark couldn’t remember what master was on Rods as it’s info Rod had. I’m using the same bearing a tilton 6000 series. My master is a tilton 76 series and it’s a .700 mark will be able to say how it compares to Carls set up. I had the use a strengthening plate on the bulkhead as normal. I also strengthened the pedal box and the clutch pedal it’s self.
