So I have been trying to order a replacement tension and pulley guide set for a shimano 105 (5700) rear deraileur. I order a set via Amazon from a marketplace seller but twice they shipped me the pulley set for the 5600 even though I sent them the part number for the 5700 set ( which is y5xh98120). On the third attempt they sent me a pulley set for an Ultegra rd-6700 (y5x998080). My question is the Ultegra pulley set compatible with the 105 5700 deraileur? Or should I try a fourth time at getting the correct part?

Thanks Simon
