Occasionally I see NOS rotors on Ebay and elsewhere. Should I buy one there instead?
If you do you should still have it rebuilt. These rotors are decades old and the primitive lubricant that was used back then is almost always getting dried up. I’ve seen NOS rotors that are very noisy and barely run. Even when I sell NOS rotors they get ultrasonically cleaned, lubricated with synthetic lubricant, sealed and bench tested.
