Do not buy this kit https://www.amazon.com/gp/product/B01NBB7AQY/ref=oh_aui_detailpage_o07_s00?ie=UTF8 It has too many sizes you do not need but do not have all the sizes you do need. W123 A/C needs #6, 8, 10, 12 SAE o-rings and SAE wrenches except 2 fittings on the expansion valve, which needs 17 & 22 mm wrenches of which there are no SAE equivalents.
