So I went to change my transmission oil today only to discover that I have a T70 plug instead of the standard 21mm plug. I could only find the socket online at one store and they wanted $45!. I just can't justify spending that much on a socket I will pretty much never use.

Does anyone have one I could borrow/rent in northeastern CT? I'm in Storrs if it makes a difference.

Alternatively, can anyone tell me where I could find the socket for significantly cheaper than $45? Thanks.
