I have a nice set of 47 Cady bumper guards listed on E-Bay. Check them out.
Does anyone know if these are the same as the 1942 bumper guards? The rears appear to be close, but I think the 1942 front guards are a bit larger.

1942 guards are different. There is a small sideways "flare" where they meet the bumper. I suppose for 1946 it was decided it was not necessary.
