total cost update I got everything needed for this project including the hydroboost unit, master cylinder, brass tee, all the hoses, and even clamps for $260 shipped from rockauto.com.
Hose from hydroboost to pump Holy crap! On a '87, that pressure hose from the pump to the hydroboost is a whore to get on! It is nothing like the routing of the original. I ended up only taking off the serpentine belt and the belt tensioner pulley and managed it but I don't recommend this project for a novice. Surely there must be a preformed pressure line from some other application that might work better? Other than that little nightmare, the upgrade was pretty straightforward and I recommend it to guys who know what they're doing or know someone who does. Nice thread... I referred to it repeatedly.
If you guys want to try and help I posted this thread in the brakes section! http://www.turbobuick.com/forums/br...dal-after-first-inch-car-off.html#post2887951
