Help ! Im having hard time figuring how to install rear pads onto an 06 arctic cat 90 DVX. Ive got a new set of EBC pads (FA197) that a local shop provided and confirms are correct. Problem is I cant find any way for the pads to stay in position and they are not equal in shape. One pad has an extended end with an open end that looks like half washer. There is nothing I can find on the caliper to attach the open end on the pad. Can anyone help out with pictures of what the stock pads looked like or how they should be installed. Thanks ahead of time.
