Hey to ya`s, I have a disc brake conversion with single circut 120 setup. What kind of master cylinder is a good choice to use with hanging pedals and is there any need to use a power booster, "hopefully not". Engine is a B230FT standing straight up via a modified bell housing . The rear end is a modified Ford Ranger, Transmission is an AW71. There is plenty of room on the drivers side for the master cylinder and just enough to use a late 240 booster. I have a 140 booster also but finding a replacment might be more dificult down the road. I was thinking of using a 70 ish Chrysler master cylinder by itself. Piston size in master cylinder needs to be matched most especially to the front calipers but not sure wich size. I know turbobricks is a good sorce for the modifications but there are some folks here who are driving the modified brake system pv`s. Thanks for any and all help. Larry
