Greetings all. I have Herm's MC kit. One thing that I found was that the arm for the brake actuator (the one with the hole in the top for the brake pedal and pivot on the bottom) hits the bracket before using the full stroke of the master cylinder. That said, when the brakes are bled and adjusted there is clearance but it is very close. I have installed the rubber washer, large body washer, and spring on the upper end (the pieces that create a seal against the floor pan when the brake is not depressed). I think I am going to take that spring out then re-adjust the master cylinder rod out a bit. That should give me another 3/8" or so of clearance between Herm's bracket and the brake actuator arm. In a past flat fender project I moved the MC to the firewall (also dual reservoir). If I was to do this one over again, I would not choose this kit. It works, don't misunderstand, but it is less than optimal in my opinion. Much like the steering box relocation kit.
