Mac 3/8 drive service set. Ratchet – extension – universal (MISSING 6 EXTENSION). Shallow – deep sae – 1/4-13/16. Shallow – deep metric – 10mm-19mm. Great used condition, didn’t notice any initials. ANSWERS ARE RIGHT HERE. ITEM DETAILS – i list items pretty accurate, but occasionally do overlook something. I sell a wide variety of items and cannot know every detail. I google details, if there is something you want to know about it, you can do the same. If listing says it fits one brand, i can not tell you if it works for a different one. Includes what is pictured ONLY unless otherwise noted. I sell for a living and know what im doing. I do not need you to tell me what my stuff is worth. I CANNOT control the post, sometimes they take way too long or a package gets stuck in limbo, but most of the time they will be delivered. I know how to pack items properly for best chance of arriving as it should. The quicker you do, the quicker i will. Well it is not right. If i do make a mistake i will happily fix it. Karma is real though.
