Looking good Karl. Far as I can see, the colour isn't too far off, but I do agree with Erich, it should be a little lighter, with a touch of blue. Wojtek hit the nail on the head re colour presentation on computers, and this also affects colour 'photographs' to an extent. Easiest solution is to re-mix the 76, add a spot of white to lighten it SLIGHTLY, then a spot of blue. Remember, when the gloss clear coat, then the semi-matt clear coat are applied, it will go slightly darker. As regards the ETC rack, hopefully the plans I sent you will have helped; the only thing I can see from your pics that I would change is the cradle itself - the vertical arms seem just a touch too long.
Good work mate.
