Seems to me they were painted black and not left as cast. Or maybe if they were painted it was mainly from one side - meaning they didn't put a whole lot of time in painting. Cars in question are my 68 and 69 RR's.
I sent mine to Firm Feel and I told them to leave it bare in case it had to stay that way. I'm leaning towards black because that's what I remember. Pretty sure the manual boxes were bare aluminum.
