Exhaust manifold support brackets for early 273

I'm looking for the two brackets that bolt to the bellhousing and the tail of the exhaust manifold on the left side. For my '65 F/S resto, I can't find them in the parts book, but here's what they look like. I'm not sure if these came on '65s, but they look like a good idea.

For some reason, they list both braces with the same part number....2465162....and they say only one is used per car! Maybe the replacement part was just a tube you had to cut, bend and drill?
