Anyone have a equivalent part number or alternate for the two brake shoe return springs inside the brake drum.

McMaster-Carr didn't show anything similar, but I did find this:

Thanks Chunk. I spent the day in 5 different auto stores, nothing close. Mcmaster Carr had a stainless spring with a little difference in dimensions but not sure about the tension of a stainless compared to a steel. Reluctant to use that .

The EBAY one looks promising.
