OK, i'm pretty sure this will be the last thing i need to replace since theres really nothing left to buy besides rotors and drums...
the MC is fed fluid from the res through 2 hoses that plug into it with a plastic elbow and a small rubber grommet:
as i found out last week, mine are leaking... its barely visible in this pic... thanks to Bill K. from the 411/412 forum i found a website that lists new ones for about $3. i got lucky this time as its the same part used on certain type 3s. hopefully they will be here by the weekend when the weather is supposed to dry out a bit.
i guess its kind of ironic that after all this work i'm not even going to be driving it... not until the engine and suspension are rebuilt. one less thing to worry about later...
