The rod was adjusted to its shortest length and was still to long. I spoke with a guy at CPP this morning and he had not heard of this problem before, to short yes, to long no. He suggested cutting an inch off of the pedal push rod which should work, the thread inside the push rod looks deep enough to allow for that. I will go over my installation one more time to make sure I didn't make some boneheaded mistake before I bring out the hacksaw. The brackets for these things mount on the two holes that held the original master cylinder on so I don't see much room error.
I have a drum/drum brake system and Classic Auto Parts sent me a booster with proportioning valve which I don't need. You gotta watch these guys. Martin
