well I am getting the whole drop out year end out of the si and I would just as soon use the same prop and mc that the actual car used for now until I get a lil more edumacation in the brake system workings.....but I guess I will schoop up the MC and Prop this week. the guy wants 200 bucks for the rear disk swap with everything including sway bar and e-brake cable with lca's yadda yadda.....and then another 35 for the prop valve....good deal?
