Wanted 7/8" NF left hand thread nuts

Or try McMaster-Carr.

I would also have included McMaster if I believed it would have helped, but they have refused to ship to Canada or even to a US address if they believe the product will eventually end up in Canada (for example, if your credit card has a Canadian billing address). Maybe their policy has changed.... but I have a long memory for unhelpful suppliers.
