USE: 0130-3012 (3) Supplier has changed to a different colour block , beige, with slightly different geometry It has tiny wings at the sides that are supposed to help reduce noise at idle It is always possible to replace just one block but it is not a good idea for 2 reasons: 1 The weight of the block is not exactly the same, so it might create an unbalance issue 2 Since all 3 blocks wear together in the product, it is always better to change all 3 at the same time to ensure good performance
