You might check with shoup, Stanley or A and I online catalogs to see if they give dimensions that would be close to what you need. Years ago I had a Massey 300 Hi Lift and the exhaust manifold rusted out completely so I built an exhaust header and topped it off with a cherry bomb glass pack muffler. It sounded pretty good and was better than giving up the thing

You need a muffler from a D10/12 Series III. 7" oval. D15 III is 9". Been there done that

These oval H-3 mufflers could be made from Stainless Steel - I have the dimensions for the components inside of the muffler. Calvin has supplied the correct info for the outside dimensions. They would never wear out in your lifetime.
