Don't overthink it. Super easy to take the MC in and out once you have the pedal box installed and your brake pedal lined up. Then check the clutch MC with the pedal stopped before the 3/4-inch chassis tube. I like the clutch and brake pedal to be the same height. Likely you'll need to cut the pushrod some to get it far enough into the clevis. Mock-up will show you how much. Easy.
