Which seal for disc front brakes?

Have a 70 Cuda with front disc brakes. Will be changing rotors during winter. I found the correct inner and outer bearings, but mixed up on which seal is correct. All the parts guides that I can find including Rockauto show different seals for 10 inch or 11 inch brakes. Does not say which one for disc brakes.
So for those that know, which seal is correct? Please give a brand and part#.
Thanks.

The disc brake spindles are unique for the disc brakes. Buy the seals for the disc brake rotors, might have to look at 71 Brake rotors. The 10" and 11" drums have different spindles as well.

If all that fails, do the bearings for the rotors match the 11" brake bearings? Gene

Im told that the 10 and 11" bearings are the same for drums and disc. Now the seal is a mystery.
Even the catalogs say bearings for 10 and 11 inch brakes are the same, but no mention of disc brakes.
Hope someone knows which seal is correct. Don't want to buy both sizes.

Cass has the wear rings bearings & seals!

If necessary, take the old ones into a good NAPA store and they will match them up. Likely to be in stock... or order from Dr Diff as mentioned.

The seal for 11" drum brakes is correct for disc brake rotors. John.

Thanks for the answer. Finally looked up specs for the 10" vs 11" seal. The inner and outer diameter is the same for both seals. The shoulder is a bit wider for 11" brakes.
