Very interesting. They cut off the eye bracket and extended it about an inch. I guess that means that the stock setup does not use all of the available stroke of the master before the pedal is on the floor. They must have done this to move the pedal out giving more pedal throw translating to more of the stroke being used.
@Columbia Cruiser must be affiliated with Jonesey's as he is spot on with your setup.
Tonight both my NV3500 and NV4500 slaves came in. The mounting flange is identical. The NV3500 push rod is 4" where the NV4500 qis 4.5"...they are interchangable if need be.
I removed the pin and quick disconnect, and replaced with a russel -3AN adapter fitting. I am going to run a flexible -3AN line to the frame and the adapter to the standard Inverted flare M10x1.0 and run a hard line to the master.
