I have a question about the gauge cluster in 1971 fuselage Plymouth Roadrunners. In some of the gauge clusters I have seen there's always a speedometer far left, then to the right of that is sometimes a tach, and sometimes there's an oil gauge and fuel gauge in the area where the tach is.

So my question is, are both of these correct and the build sheet will tell you what the orientation of the gauge cluster is? Can someone help me out as I want to know what the deal is with these gauge sets and how to tell them apart. I've included photos both ways to explain what I'm talking about.

Thanks!!!!!!!
