Hi all i have a 1987 ae82 corolla hatch,i am looking to replace the rear drum shoes,but according to the people at repco,theres is like 4 or so to choose from i am just wanting to know what is the most common (example bs1065)? and do they actually interchange? like if i get the wrong shoes,will they still fit?or what do i have to do to make sure i don't get the wrong ones?any help would be great thanks
