Working on getting the car back together and ran across a couple of things that confuse me. Start with the disc brake piping...I have all dated components proportion valve, distribution block, 309 MC. Bought a stainless line kit from HBC and am now thinking I either chose the wrong kit or they shipped me the wrong kit. The fitting sizes and pre-form bends don't jive with what I have. Before I call them on Monday, can someone confirm a few things based on what they have? My MC has port threads for a blue fitting on the rear and a green fitting on the front. My proportion valve has a green fitting on front and back, brass colored on the two front sides (both those matched the lines I rec'vd) , and a pinkish fitting on the rear side. My prop valve has pinkish fitting size threads on both the front and side (poor sketch attached). Don't pay attention to the two lines in the MC, just there to prevent leaks.
Firewall - there is a hole in my new firewall pad centered over the tunnel. There is a somewhat corresponding hole in my firewall - what goes in there? There is also a small hole to the inside of my speedo cable clip. What goes there - I don't recall removing anything from these spots when I disassembled the car.
