Exploding Torqueflites

okay guys where can I get a 6 bolt sprag for a 904 ? and now for the real noob question can I get a valve body that is manual in 1st and 2nd but auto in drive/3rd , would like to be able to burnout in 2nd but still be an auto for daily driving , already ordered the steel drum and 24 spring return module kit and the deluxe racing rebuild kit from TCS here in Canada just need to find the rest before the new motor gets here thanks -Chris
