How do I tell what size rear brake shoes I need for an '89 toyota pickup ext cab w a 22re, AT and 360K on the odometer? I've already thrown away the old shoes after beating on the drums w/ 10# sledge hammer. Pulling the truck wouldn't break them free after they sat since last January. When I looked at Rock Auto and called Azone I was informed there were two (2) sizes and hardware kits. Just replaced an axle, front wheel bearings/races and the ball joints trying to get it ready for winter. Thanks
