Norm, I guess you were about as close my neck of the woods as you're gonna get, going down to D.C.
The switch I'm talking about is one of these:

Still available new from GM, although not as good as the originals. I had trouble with one of these shorting out internally once. Made lots of smoke under the dash of my last Starfire convertible!

Can't buy them from GM for what this seller want, tho. Single switch for the passenger side is also available.
