Interesting and informative thread on the DG4 mirrors. I'm just not sure how many different types were made, but I think GM got them from a few various suppliers and just called them all DG4.
Here's one I found on ebay, supposedly original and I don't doubt it, but it's not what I was after.
What's left of my original 1971 Drivers Door DG4.
And the one I found, but it's not what I was after . . .
