I've an unused STDX645 and two maybe used once or shelf wear STDX427 hard handle in Orange. Unsure what "new instinct" means. It is only part of a set but you'll likely find others who sell/trade singles or pairs on here. Just in case, I also have an SDTX40 mini set in Green, and a single SDT 309 and single SGDT 320A for trading. Looking for a nice SO Ratcheting Stubby, Williams Super Palmster or SO equivalent, SK 45127, even 7mm, 8mm, 9mm, 15mm, 17mm, 1/4", 5/16", 5/8", and 11/16" Gearwrenches. PM, maybe we can work something out and save each other some money?
