Hi i have a 2008 Subaru impreza and it has 138000 miles and its about ready to have the rear brakes done. It has drum brakes and i am having a hard time finding the hardware kit for the brakes.I can find the parking brake hardware kit but not the one for the drum brakes itself. Any help on this would be helpful. Also i have seen some things on upgrading to disc brakes is this a big project or should i just leave it alone as is.Thanks for your help.
