If I remember correctly Roolieb (http://www.rootlieb.com/running-boards.html) was making a limited run of a very high quality 1930-31 running board (as Brent said you forgot to include your year). How high of quality do you want?
Rootlieb makes a great 31 board but to johns post
At least the steel is not from an original die; very distinct differences
As to the pyramid rubber I doubt that is from original mould as it would not work on the non-original steel. Unless all of this changes in the new run that I have not seen yet
One of the best repo parts out there all in all
