What's with the two holes in these distributor tags?

[cruiser]

Hi All: I know this is pretty minor, but I'm curious about the holes in these distributor tags. Both distributors that I have for my slant six (October of 1973 build) 1974 Duster have these two holes that you see in the photos. The part numbers on these distributors are correct for a California emissions, and for a non-California emissions car. Both aluminum tags have two holes: One in roughly the top center, the other offset to the left (see photos). The holes offset to the left appear roughly drilled and have a ring around the holes as well. Does anyone know why there would be two holes in a tag fastened to the distributor with only one screw? And why does the other hole look so poorly drilled? I have no reason to believe that a previous owner put the extra holes in the tags. Ideas, anyone?

It’s possible that they used the same tags for B,LA and S6 distributors ? Requiring multiple mounting holes for different applications.

IMHO...

The "poorly drilled" holes were the holes that the tag was attached with.

Aluminum tag being thin and soft distorted from the screw head twisting and smashing the tag
