West Coast Choppers say they don't touch cars beyond a certain age -- does anyone know what age that is? - west coast choppers bicycle

I remember them saying something like "do not touch the cars later than 1942" or something. I do not remember the date. Does anyone know the answer to this question? Thank you.
