I don't have any extras but here's a pic of what you need . The top one is # 40-18047 and is 33 front , the middle is # 40-18052-A and is 33 and early 34 rear and the bottom is # 40-18052-B and is 34 rear only . The rears will interchange if you use the link for it . 33 takes the links with holes on opposite sides and 34 takes links with the holees on the same side . You need the one in the middle . Good Luck David J
