My STI MC&BB came in today. It's going to sit in the shed until spring, but I got the brake booster, master cylinder, and the vacuum hose with check valve from ebay seller silverlineparts here: http://www.ebay.ca/itm/370282909074?ru=http%3A%2F%2Fwww.ebay.ca%3A80%2Fsch%2Fi.html%3F_from%3DR40%26_trksid%3Dp4712.m570.l1313%26_nkw%3D370282909074%26_sacat%3DSee-All-Categories%26_fvi%3D1&_rdc=1#ht_1080wt_290 (No affiliation, just a happy buyer)
I'm looking forward to installing it and feeling the improvement!
