i just bought a C-N dash 9 and a sd40. i had been under the impresion that the grab irons and the ends of the hand rails were suposed to be D-H gray, but in rail picts.net the front stantions look orange and the end hand rails look white. it also apears that on the long hood the stantions are either black or orange and the hand rail is white. ALSO what does the back end of the long hood of the sd40 look like. do i fill it in lke all my S-P units and make it solid orange. if any one can answere any or all of these questions it would be most helpfull
