Am doing some clean-up on my 67 S and keep getting deeper and deeper into cleaning (just got a new steam cleaner Anyway, I have all the tin and other items at the sandblasters getting ready for some cleaning and respray. My question for colors are the fan strap ( I recall black although on my later cars its gold cad plating), fan surround and fan (are they protected by maybe cad plateing??). And the heatexchangers are to be a grey along with the muffler (there are signs of grey for a match on them).

Appreciate any advice here ...or pictures are even better.

Thanks
