Just put a new aluminum MC on my Duster. If your going manual disc/drum get one from an early 90's (90-93) B150 van. It's got the right bore size (1 1/8").
$30 from rockauto! Then just get the 4 to 2 bolt adapter from Ehrenberg/Summit on the old interweb. He's the one that recommended the MC above to me for my car and it stops great. Great pedal feel. Glad I ditched the numb/heavy/power robbing power steering stuff while I did the motor and front end refurb!
