If they are mounted on the KKX or DOZA-B spindles then they fit. At the very least they are a good starting point and rare in their own regard. If that is the case then you can press the studs out , detail the hubs for originality and then install new rotor hats (NPD now sells some by themselves) and press the studs back on and after having them turned to true up. The rotors are needles in the haystack now given Branda and NPD are out of stock of the replacements Tony Branda had made up years ago . i think it took more then 10 years to sellout the first run . i was told by Tony before his passing that it was too big of a investment to let sit that long so don't expect anymore replacements anytime soon.

I have one DOAZ 3108 B and one KKX [passenger side] they appear to be coated withs some sort of aluminum paint/coating which makes them look ugly---rotors to me appear to be original and in fairly good shape--rotor on the other hand are blue in color and most likely fake---I have in my warehouse BENDIX-FE 776-AO, but am not sure if this is correct---thus I need one DOAZ 31O7 one set of pads and someone would have correct rotors I would buy them also. in retrospect if anybody needs KKX or DOAZ 3107 B spindle I  would be willing to part or trade them--thanks

Here are a couple of pics of an original rotor and a new repro like you are looking for. Notice the factory slapped on blackout.

Thanks--- I have no idea difference between original and reproduction--my aim is original if can only find it and can you please point out the difference--thanks --John

The main thing that jumps out at me is the face of the center portion of the rotor is flat on my originals and the repro rotors. I'm not saying yours aren't original just I have never seen ones with the recesses yous have. Others may have seen them.

If the rotors fit on the special KKX or DOZA-B spindles then the rotors are the special ones too regardless of if assemblyline or aftermarket. The most important thing is to have something that fits in this world of even finding a aftermarket will be difficult . I would repair/restore the ones on the car now if need be. I have a pair of aftermarket Shelby rotors on my shelves for save keeping in case one of my cars needs them. I am sure there are others like myself but it may be difficult and expensive to try and pry them loose unless they have sold the car etc. The point is for the uninformed is that ether type of special rotors are hard to find and you shouldn't pass up a aftermarket one in the hopes of finding a NOS original. You are looking at lottery ticket odds finding NOS special rotors IMO.Even finding used original ones to rebuild are likely only smaller less lottery win odds. Original are not marked with a Ford trademark or engineering number and the subtle nuances differences between the aftermarket and assemblyline are small. Once wheels are mounted even the subtle differences disappear. If every other thing on the car is original belts,battery,tires etc. then maybe it may make a difference other wise it will not effect the big picture much IMO.

Blue no. Gray pad material with zinc gold metal.

Those would be very close in appearance to original assembly line. Bendix was a OEM.

Take a little time to remove the wording on the edge - just in case its visible (likely isn't but don't run the risk) once installed ;)   No reason to run the risk since it is so easy to address at this point

The original front brake pads were glued on shoe phosphate metal with fomoco stamped in corner. 68 (c8oz)were small pads then later 69 (c90z) full pads with the c9az stainless steel clips on the ends then early 70s ford started using riveted shoe pad service dooz kits that were the goldish plating and 70 -73 used several versions and #s dooz kits. ford sold the pads separate and with the shields and hardware as a complete kit and a dooz kit that had the shields and hardware without pads.

I, too, had bought a set of the reproduction rotors that Ed had a hand in getting made and put them away. I have the originals on my car still with 105K kilometers on it. I also remember when buying my 70 Gt500 in 1984 the previous owner told me how he had to press off the disk and replace it on one of the rotors on the car many years earlier in the early 70s. I thought he was crazy doing that not knowing about the boss rotors on later Shelbys. So I would guess you couldn't get replacement rotors back in the early to mid 70s. Kinda like trying to find a 69 Boss 302 quarter panel in 1972. Gary

John the rotor photos on reply #5 are 1970 and up dooz rotors that fit on 1970 doza 3107 & 3108 -c  spindles that will fit (but not concours correct) the 69 b2 b9 and big suspension Shelby cars that use the big stud tierods and bigger drag link.  This setup is what people used back years ago when they counldnt find the original unique late F-60-15 69 Shelby rotors.  U can still find 70 spindles and rotors since they were used on all 70 mustangs and cougars with disc brakes.

Just looked at my nos c9zz-b rotors (first time in years) and one is like johns photo rotor (so it maybe correct afterall. My other nos rotor is the one I sent out to California to have them made for branda years ago and  the hub face is a little different smoother and don't have the cross hash marks in between the 5 studs so I am wondering if a running change  or  a different vendor. The rotor hub type in johns photo is like the ones used on 70 doza-c spindles like on the 70 boss cars. I have seen many late 69 shelby f-60-15  Xhd suspension cars that had one side shortened KKX spindle and the other side doza-b spindle so I am wondering if the later doza-b spindle used the 70 type hub (with the hash marks ) rotor that was machined for the bearings to match the spindle.

Hi---my driver side rotor to me it looks same as passenger side even though passenger side has KKX spindle, and driver side has DOAZ 3108-a with B in next line

John your spindles and rotors look correct and they can be mismatched  kkx vs doza-b as I have seen that before many times. There was a double wrapped brake caliper wire twisted together as an earmark on assembly line to id these unique spindle rotor combo on the late shelbys and boss 302s and this wire is often removed by past owners if the cars been worked on.

Tobkob I noticed your rotor hub doesn't have a hole in it does it and is it the early c80z type or c9zzb type for late Shelby?

They are the large suspension...KKX spindles... built April 7th...

I don't remember since it has been 5 years since I have seen them. As I recall they are the same as the repro set I have. Post a pic and I'll see if it jogs my memory.  ::)

I just looked at my nos c9zz rotors again and there must be 3 types the 2 groove (like TOB photo) the 2 groove with a hole then the type like johns photo 2 groove with the 5 cross hash marks between studs and a hole. I don't know why ford didn't ID  the hub rotors somehow to avoid all the confusion between the 68 69 70 cars was 4 hub rotors but they did ID the spindles.  I have 2 different types of hub rotors for the 70  boss mustangs here also.
