I was at Delco-Remy in the early 70s and there was a big move on to reduce 
the number of part numbers. At the time there could be five or six 
different part numbers for the same part resulting from slightly different 
finishes or a minor bend somewhere or a slot instead of a hole or sometimes 
we never found any difference at all.

Since DR (not Chevrolet) made the headlight switches, it is likely that 
this is what happened. You would need to look at the original assembly 
drawings to see what the difference was.
