Anyone ever disassemble a distributor - need help

Not upside down, but the roll pin that locates the reluctor on the shaft can be put in the wrong slot causing a phasing issue.
The arrow and two lines is where the reluctor roll pin goes for small blocks, and the other slot in the reluctor would be for big blocks. (that way the same part can be used for either small or big blocks)

So if you turn it over, you get the lefty arrow over the other notch? Thats how I remembered one I saw. I think Sheppard's book references this too. Something to check on a reman for sure.
