There are dimensions and calipers around, but you really need to have them matched to the rotor being used. There are offset variations as well as different OD's which affect the mounting.

Here are the brackets, sideways to make it harder on you. The dimension on the rear bracket(black) that is flared out is 76mm. I wish I could have made the CAD program work, but that's for another day. These are wire cut and then machined and anodized.
