Than, Bendix is correct

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.

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?

Is there a hole in the hub of your rotor?

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.
