So I went to my local napa (all I have for a parts store here in the boondocks) asking for a T70 socket. Only thing on the shelf is a T60. Asked him to check his impact sockets in the book and he found a T70 for $6 (rounded figure) Ordered it and recieved it the next day. Part number is 61-5470. Thought it was a really good deal for a impact rated T70.
