I haven't been back to my storage yet , so I don't have the p. # yet but your right about the $ , I used to buy from the snap on truck becouse if they made it , it was usally the best , but then the that the used to have was alot of what the extra was , now theres not much of that, and when my dealer saw how much I bought from him , it put me at the top of his deal list. so now back to your issue , now I go to there supplier every time I can , for that part I'm not sure but I think it comes from either OTC or SPX , usally the tool guys will carry those catalogs so have the truck of your choise look it up becouse I'm perty sure that snap on does not make it.
