We are confused on what parts to order when replacing the front drum glide or bearing assembly. Our dismantled dryer has worn brackets (3 sided, attached to the front bulkhead with rivets) and no visable pads on the brackets (did it have some at one time?). We are guessing that we need to order parts AP4010165 (brackets) and AP2403213 (pad), but want this confirmed or other suggestions before ordering. Thanks.
