The voltage regulator I can'r remember for sure but I think my original is black w/yellow stamped lettering. I replaced it in the 70's w/a mopar one that's black with a label, that says mopar on it. Don't have picture handy, sorry. The master cylinder cover is aftermarket & that means the m/c probably is, too. if it has the little raised bump out at the end of it, it is. I still have my original (I never seem to get much thrown away) but the one on my car is aftermarket but, it came with the correct cover. I think I put it on in 1980. The one on the orange car is original.
