Can anyone help me ID these? I purchased them to use on my 65 wagon and can't remember the specifics.

I've looked at the various resto suppliers and haven't found a match. I think they were nos or repo 65 hangars for dual exhaust......but every place lists hangars as 64-72?

They have canada stamped on them.

Thanks for any help, Kevin
