Well, since I'm leaving on Saturday for a 2 week trip, I need something I can get shipped to me within 2-3 days ... so back to Amazon Prime I went. With your experience, do these sockets look thin-walled enough that they'd work on your Cougar (and by extension mine as well)?
They "look" thin enough to me to work, but you can never tell with pictures.
