I'm not familiar with that "fix", and have a hard time imagining what 
it might cure. The only thing I could imagine doing on the outside of 
the sender would be to add a ground connection, but I've never seen 
that to be necessary. (You've already noticed that VDO has a 
provision there for a ground lug. That was never used on our cars, 
but I suspect VDO used that same casting for lots of makes/models. A 
ground lug would be necessary on plastic tanks, but I don't think 
there were ANY plastic tanks in this era, so I'm not sure who would 
have used that lug.)

If they were just running a wire in thru that hole, there are much 
nicer ways of fixing that problem, and that's what I do when I 
rebuild one of those senders.
