My 1966 TR4A has Royal Blue paint & Midnight Blue/White interior. I have found sources for matching replacement seat covers & trim but the closest carpet color I can find is Shadow Blue. The parts manual describes the factory carpet as Midnight Blue (or red or black) and I can see from the protected areas of my original carpet that Shadow Blue is not a match. I have tried Moss, TRF, Heritage, John Skinner, Coverdale & Newton Commercial. Any ideas on a source or should I give up?
