Thanks for taking the time to post. Interesting use for a faucet wrench - sort of a self-adjusting crows foot. I've personally found these almost useless on corroded faucet nuts, perhaps it might get more use if I threw it into the car tool box.
p.s. I've brought your post to the attention of another member, recently/currently involved with a late '95
mtx VSS, perhaps he can oblige re hosting your pics.
