Exhaust pipe clamp

Vic, my opinion only, but I used a rubber "cotton reel" exhaust mount under compression. Mounted through the standard clamp hole in the chassis rail and sitting inside the rail, on the bottom chord. A U bolt clamp on the pipe is then configured with a short steel strap to bear on the cotton reel. This allows some rotation in the exhaust as well as lengthwise expansion as it heats up.
A photo would explain it better if you are interested.

Cotton reels aside for a moment, I open up the clamp as far as it will go and wrap the pipe with a single later of paper or cling wrap (might have to use adhesive tape to hold it there). Then I insert 2 or 3 wooden wedges in the gap so that the pipe is centred in the hole. After that, I fill the gap with silicone, let it cure, inject more to fill the holes left by pulling out the wedges and away I go for the next 30,000 miles. To make removal of the wedges easy, I wet them before inserting them. Some silicones are harder than others when cured. I use a hard one for longevity.

Photos as requested. Two are of the cotton reel rubber, the other 2 are under my roadster using flat steel and a piece of canvas reinforced rubber. Probably cut from a car tyre or a piece of industrial belting. I cannot recall.
In both cases longitudinal expansion of the hot exhaust is permitted. Rotation is limited about the pipe axis but the manifold downpipe expanding and rotating the system in the longiitudinal plane is permitted.

Vic, take a look at this thread and see the post down the page from Al in NY where he shows a photo of a homemade hanger that he made. I did the same. It works well.

Just use one of these rear exhaust clamps (from Brattons)):
It looks kinda close to an original and the heat insulator will keep the exhaust pipe from rattling, but, if tightened properly (not too tight and with the cotter pin inserted), your exhaust pipe will be able to move around with the movement of your engine and the expanding and contracting from the exhaust heat.

I had a clamp like this on my Town Sedan and it never seemed to fit correctly. Then I installed and Aries muffler and it fit perfect.
All along I was blaming the design of the clamp and tried different remedies and it turned out to be the gyp muffler and pipe was the incorrect shape
