K you don't need to wonder what you need simple you have the four bolt type spindle if you have drums the two bolt type of you have disc.  Therefore you need MSteve's brake braket kit if you want 17" wheels if you want smaller then Steves making the new kit to fit in 15" wheels at least he was going to do this.  Or if you want 15" wheels you can use the stock Kelsey Hayes type Pistons with the bolt on caliper brackets and the misc hardware like hoses the proportioning valve.  You mentioned going to power disc in that case disconnect the speedometer cable from the cluster remove retaining screws and pull out the cluster. Then remove the retaining screws for the column.  Then disconnect the master cylinder from the support.  After this is done inspect the pedal hanger for ware as they are known for this.  If the centering bushings are bad then Steve has a awesome fix for it.  Then you'll need to drill a hole in the proper spot then you need to purchase a pedal pin and other misc hardware which Steve sales.  And the reinforcement for the hanger which he has.  After all this then you'll need some 3/16" brake line as I would replace it all.  You'll need a flare nut wrench double flare tool and flare bar reamer and other stuff needed to function as well as a file.  Theres videos on YouTube on how to properly flare.  If you have a single flare bar but not the double flare adaptor those can be had online.  For line the copper Nickle plated lines bend awesome flare great and are supper easy to straighten out if it's a roll.  I purchased my line from a company called evco house of hose. 

For a disc drum master the proper one to use that fits great and looks era correct is the 67-70 style mustang power brake master which has a 1" bore. 
If you want a disc disc set up the most used master is a 2000 mustang v6 master which has a 1 1/16" bore if I remember correctly.  the fluid resivour MS likes to switch out I don't recall from  what model of a car even though it's been talked about numerous amounts of times.


This is the basis of what you'll need hope this helps

SA69MACH yeah I definitely plan to put a booster on the master cylinder. Jo

Good plan.  Have a look at this page from Mustang Steves site to learn about the minor but important differences of the 70 power brake pedal and boosters.  The 70 booster and pedal is a matched pair. 
I know from recent and current experience the 70 power brake pedal can be difficult to find.  The ones on ebay say they fit a 70, but neglect to say it will fit only if you use a 69 booster.  That setup is a good option for you, since you do not currently have a booster, so keep that in mind when you decide to buy the booster and pedal.

A good disc brake conversion kit will have all, and only, the parts you need.

You guys are awesome. Thanks for all your help. I can get discount auto parts thru carquest thru my son so that's great. I guess the next question is for steve then on what parts I need to set up a factory discs. I wanted to go with 11" but if its going to interfere with putting the 16" cragars on it I dont want to mess with that. I what type of a setup are you talking about with the master cylinder and booster?  Anything OEM part wise I can get thru carquest so please elaborate. So I can decide which way to go. Thank you. Jo

Factory discs will fit fine. They would even fit a 14" rim of you wanted.  The brakes are the easy part.


You'll need a 9/16" deep socket cotter pin puller a 1 1/8" socket if I remember correctly deep 13/16" socket braker bar and 3/8" drive ratchet and some vise grips help.  Pull drum off then use the vise grips on the head of bolts as they don't have a hex head on them.  And then remove them.  Then the drum backing plate should pop off after removing the brake hose.  After this is done the stock disc calipers use a four bolt mounting bracket that bolts to the spindle and then the calipers bolt to them.  Then the rest is pretty plug in play besides the line routing and the mounting of the proportioning valve.  harbor freight has a brake flare tool. Make sure if you get it or even different brands as several had a problem the hole was drilled off set and so the slot for the line would be oval no Bueno.
