Hello everyone, Looking for some feedback on replacement disc brake rotors ala '70 Hurst. Local parts stores have several different ones available but all have to be pre-paid and special ordered and Im unsure which one(s) will work. These are all new parts made by several different manufacturers and 2 distinct styles. They are as follows: Raybestos 1 piece # 7018 $71.99 Raybestos 2 piece # 7012 $131.99 RayMold 1 piece # 10-7018 $47.99 Ainco 1 piece # 5307 $ 26.99 Has anyone had any luck replacing the 2 piece rotor with a 1 piece? Whats the differences? Can these all really be interchangeable? Thanks Mike Laiserin
