This is the backing plate to which the caliper for the disk brake attaches. Note the white areas. These areas need to be ground off to clear the swing arm. This item is also painted blue in most other pictures on this site. The center hole must be re-bored to 2.30" dia. Remount using existing bolts. Do Not grind all backing plates the same, two ( if using four) backing plates must be ground off the opposite of how Fig. 1 indicates.
