I posted this a couple times in the past:

Pre '73 C-body 11.75" x 1.25" rotors (ie Centric unicast rotor #120-63021) will bolt to pre '73 B/E body disc and drum knuckles, as they share the same wheel bearings.

If you replace the Set 6 bearing package with a Set 13 version, these rotors will bolt directly to '73 and newer A,B,E,F,M,J and R body spindles.

In addition, you can bolt the cheap/commonly available '73 C-body/pickup/van 11.75" x 1.25" rotor to a '73 and newer A,B,E,F,M,J and R body spindle by using the OUTER wheel bearing adapter sleeve I produce.

I built a one-off brake kit using these rotors and second generation Viper calipers, but because of the additional clearance required by the massive calipers, 15" wheels would not fit.

If first generation Viper calipers were commonly available, I would build a brake kit around this combination.




Cass, I bought Andy's kit to install the First Gen Viper calipers onto 73-76 A body drum spindles from you last year.

If I get the Timken Set 13 bearings for the outer bearing from you I can install these 11.75" x 1.25" rotors and ditch the brake pad spacers and have more mass to absorb the heat.....

I will call you Monday Cass...thanks for posting.

Now I have a call out to rotor pros to see if they sell this rotor in dimpled and slotted......

Unfortunately, I don't think the C-body 11.75" rotor shares the same offset as the B-body version.

FWIW, although I didn't measure it exactly, I think I gained 3/8 to 1/2" in tire/fender-lip clearance after I installed the '73 C-rotors on my '73 A-body (disc spindles) in favor of the 10.9(?) rotors.
Besides the outer bearingsleeve on the spindle, the only other thing I had to do was putting large washers between the caliperbrackets and spindles to make them clear the rotors.
I think the washers were about 1.5mm thick (0.060")

If you want C-Body rotors seems to me it would be a whole lot easier to just use a 73 c-body spindle . If you can find them? Just slot them to suit the lower ball joint, easy to do? Took me about 10 minutes each to do them on the mill.

Since they are taller, I think they probably not work with 5.0 or more backspacing.

I know the C-body and B-body caliper brackets do not share the same bolt pattern at the knuckle. I don't know if the offset is the same or even close.





What about the truck/van caliper brackets? Has anybody looked at them?
