I looked at that chart above and I'm now confused.
The first one posted show the 534 as a chrome box, but I'm about 97% sure I have a gold box with that part number on it.
I know that gold box I have was used on the street. I was thinking about it last night laying in bed and I'm thinking where did I get that box? I never bought one of those.
Then I realized the car I have now came with that box on it. My cousin owned the car then, and he wanted a two step so we took that off and bought a Mallory box.
Of course, my cousin was like a fart in a skillet and we never got around to getting a two step in the car.
So that particular gold box was used in the street. For quite a while.
