    Front disc rotors

    I bought front disc brake rotors for my 66 fastback and had to order from 2 different places due to availability. When I received them one has the front hub built into the rotor and the other is just the rotor. I took the hub off of the original old rotor and if I install it the measurement from the braking surface to the end of hub is the exact same. They look different but will they work okay being different or should I search for a matching rotor with hub built in?  Going to use orig Kelsey Hayes front discs.

    Re: Front disc rotors

    OEM rotors were of two piece construction.  Replacements are, by and large, one piece.  They are interchangeable except for the studs.  I have had one of each on my car with no adversity.   Bearing size is the same and hat size is the same.

    Look at the 3 studs in the photo.  The top one is for the one piece rotor.  The bottom two are for the two piece rotor.  Notice the lower ones.  They have a shoulder just below the head.  The base is also longer.  Don't even try to get the 2 piece into the 1- piece rotor.  The holes are of different size.
