This was my wife's late fathers car, Now hers. I knew nothing about Mustangs until we got this one last fall. My first thought was Wheels. Then I drove the car. Definitely first thing BRAKES!!! So why not upgrade??? I don't know for sure how to go about it the most cost effective manner. I found a 4 lug Disk conversion kit but it wont run my stock 14" steel drum wheels and hub caps. So I'd be looking for wheels RIGHT AWAY $$$$. Scarebird kit I think could be put together for just under $400. but I'm afraid I'll be setting with a bunch of parts that wont go together. Id also Like to add the booster but I saw a kit that included a new brake peddle and I'm not sure why. I'll Bet this has been gone over and over but I have not found this covered anywhere. Here is what I learned, 67 spindles can run and 4 and 5 lug and hubs can be found. GOOD FOR Future when i find a deal on some wheels. Rear Axles from the 7 1/4 dif. can be modified from 4 lug to 5. GOOD FOR Future. BUTT what will get her on the road this summer. I know some will say spend more. Some one will say go through the existing Drums. Please comment if you have a logical direction for me other than 15" wheels and $2500.

there are a few actually;

1: scarebird has brackets that allow you to bolt later model calipers and rotors to the stock early spindles. its an inexpensive and reliable way to go

2: http://www.cal-mustang.com/STANDARD...ION-KIT-1964-1966-6-Cyl-4-LUG-P13420C860.aspx they also have a rear disc brake kit for four lug applications as well

3: here are a couple of threads from another forum where us inline nuts come up with some interesting stuff to keep our four lug wheels;

check around on some of these links, i believe some will allow you to use the stock 14" wheels you already have.
 
The reason for a pedal is manual brakes and power brakes use different amount of leverage. You can easily put in a fox body 2.3l preferably a 5.0 or tandem later 70? model booster. If you look at mustangsteve.com he sells parts to convert to power brakes. You'll use the same pedal it will just have to be modified a bit, also you'll need the plate that you weld to the front of your pedal support as well which he sells. Depending on if you'd want to swap to five lugs you can use several disc brake upgrade kits. Your front spindles are an exact intercage for v8 drum cars. You can bolt on kh style front disc brakes and then re drill out the rear end or change to rear end to a five lug rear. If you want four lugs not a whole lot available. How ever I am in the process of fabricating one.

On that note I can't decide whether to make the kit use matching calipers or upgrade to dual piston gt pbr calipers. So it would either be nissan sentra rotors my brackets centering rings and matching single piston calipers, or sentra rotors my brackets centering rings and 99-04 v6 or gt mustang calipers.. Haven't decided that part yet.. This set up would clear your 14" rims though
 
Thank you True. I've got a few thing in front of this project so Im letting fate decide which way I go. Watching cregs list for wheel. Good luck with your kit. My 2 cent on 2 piston calipers is that GM played with them on early Cam air holes" I can say that I have one" With not such good luck. I think binding of some kind. Im in Mn. born bread and frozen to the ground but if i could help in some way. I machine. Vertical mill Lathe. Tools and fixtures. For instence I'm going to make a fixture to drill my rear axle flanges. Great site you guys are Righteous Dudes. And The Dude Abides
 
Also about the link I posted. I talked to the guy selling it. I ask why buy a 4 lug if it wont clear the 14" drum wheels and he said they will with a spacer. He didnt offer to sell me a spacer though.
 
Sense you machine, you should be a good welder. I'd purchase the mustang steve booster plate and pedal pin. This will solve the problem of none power brakes. You remove the pedal support and mast cylinder. You'll need to slightly modify the pedal support and drill a hole in the pedal for a new pin. Then drill some holes in the firewall and bam. Install and your done with that portion. Then you need a booster I'm using a small 2.3l fox booster then for you'll need a master cylinder. You can use a dual bowl on it. Most people want a 1" bore master cylinder. You can use a 2000 mustang v6 master on it this has 1" bore and is good if you want front and rear discs. If you plan to use drums in back use a 70 mustang master. You'll also need a brake proportioning valve.
 
I'd just need some 3/8" steel plate cut and drilled. I'm also working on the i6 disc conversion to keep four lugs and 14" wheels. It would use nissan sentra rotors and either dual piston 99-04 mustang gt calipers, or stock calipers that match those rotors and it would need a centering ring to make the rotor hub centric
 
Sure True. I can cut some plates and drill some holes. To save on shipping i would suggest making a template and sending it to me somehow. The centric ring i don’t quite understand. Shouldn’t the wheel studs make it the rotor concentric? Or is it that the holes in the rotor for the studs are that much oversize? If so it wouldn’t it be cheaper to make 2 small spacer for two of the studs on each wheel? Since the wheel sandwiches the rotor anyways there would be no benefit to having one for each stud. Other than they could be press fit in each lug hole on the rotor so it would look a little nicer. Or am I way off and not understanding?

Roads around here might still be covered with salt until June so my projects, there’s no hurry. I recently learned that 68 and later steel wheels all are Disk compatible. I don’t know if that’s also counts the 4 lug I6 wheels. Or if they made 4 lug I6 wheels in 68.


If I could find these wheels I'm still not positive my 67 wheels covers will fit. If i knew they'd fit for sure and i could pick up 5 wheels for $25 a piece I'd be happy for a while.

These kits are what i have found .

The hub centric ring centers the rotor on the hub it's self not the lugs. As for the wheels you can use 15" all day long usually it's the 14" which gives problems. As there are a few versions. The four lug wheels in 68 may fit some
Disc brakes cars but ford didn't have disc brakes with our bolt patterns till the 90s
 
Ah. Ok. 68 14" Steel wheels are going to be 5 bolt. I could live with that if my 67 14" hub caps fit. I have a mint set like this. http://www.ebay.com/itm/1967-mustan...967|Model:Mustang&hash=item233774d34c&vxp=mtr
I could make the 4 68 x 62 center spacers in about 20min. Material is the exspensive part, and most if it will get machine away how I would need to do it on a lathe. I think it would end up to be the same even on a CNC milling machine but you would have a slug in the center and the outer web of machining them in an array to recycle.
 
I see that makes sense on the rings. I think you'd probably be ok with out them though.. I have a design down on the v8 version using the pbr calipers now. And I'm pretty sure it will work with the I6 version I just done have the rotor yet.
