Brake distribution block

Ah ha - Wedged is correct - if you have "Mopar" style (plastic reservoir). I incorrectly assumed you had a "new style" Wilwood all aluminum MC... (It's one reason why PICTURES SAY A 1000 WORDS)

Wedged gives correct "reasoning" for the "combo valve".... but I personally don't bother with them. They're "ugly" and you won't see them on most aftermarket systems. But that is a personal choice.
