Hey chev235, I kept my dual master cylinder and opted to do without the booster, also put it in the original location w/disk in front and drum in back. Don't know yet but from all the feedback this is all I need to stop my truck safely and with ease. (Will have a V-8 and 5 speed) Good Luck! BTW Call CPP! I have found that they will not answer the e-mail, but can help over the phone.
