what are the options for converting my 1967 manual brakes to power brakes? ive already converted from drum to slider disc. looking for a OEM style comprehensive kit soup to nuts complete.
i prefer the iron master over the aluminum one just because of the look. thanks in advance.

Are you trying to get something stock or just something that will work? The stock '67 power disc B-body booster is the offset booster (Hemi booster) which commands a small fortune. If you are just looking for something that will work, there are numerous third parties that supply components.

Originally I was intending on upgrading from manual (drum/drum) brakes to power disc/drum. Now im getting cold feet thinking to keep the OEM appearing and cleaner, more compact looking manual brakes master cylinder. So, now im considering upgrading to the larger rotors up front and putting some miles on it before pulling the trigger on power brakes.
Im doing a complete front suspension rebuild first and we will see how that goes. Thanks for chiming in, it always helps motivate me when I get feedback from others like minded.

Dr Diff once again is the solution to my dilemma (most if not all of my dilemmas are caused by yours truly lol)
I pulled the trigger for a full front suspension rebuild kit soup to nuts, upgraded to the larger 11.75" rotors and slider type caliper brackets, new loaded calipers, wheel bearings and seal kit, rear wheel cylinders, front hard lines, stainless front flex lines, and the rear stainless flex line with "T" fitting. I ordered the 15/16" bore manual disc master cylinder from Rock Auto . I intend to flush the remaining system and upgrade to using Dot 5 fluids.
Last time I drove my car, it still had the stock manual drum/drum setup from factory. I'd be willing to bet I might even notice an improvement if only I haven't become so accustomed to modern automotive brakes of today.
