Inner wing hydraulic manifold clutch thread spec

[Zener]

Hoping someone can confirm that the clutch union port exiting from the hydraulic junction/manifold under bonnet side is 7/16 unf 20 and not some st bizarre size like the clutch slave M20X1 mm inlet was rather hoping its the same size as the clutch master outlet which is 7/16 unf , I dont want to randomly dismantle mine to find out because I'm using the car frequently at present would rather have a replacement at hand to just swap over , thank you

I’ve got my clutch line off at the moment and the adapter through the bulkhead is 7/16x20tpi. Mine is a 94 Griff, I assume all the later cars used the same size?
Incidentally the slave inlet is M12x1 not M20 as you have noted, guess that’s a typo?
