It has some ohm spec charts for a variety of senders. It's a Corvette forum and they also talk about the problem with the newer GM senders. They also have some good photos of the senders as well.
By the way I just took the T/A out for a test drive with the mechanical gauge installed in the temp sender location. It's around 97 degrees outside at the moment and the car ran 190 most of the way with the A/C on full blast. It did heat up a bit (the car that is) once I stopped to assist the well-dressed, damsel in distress on the side of the road who was looking for a graduation party somewhere in the area and had no clue about what road it was on.
And of course on the return trip it seemed that everyone in the area who had a lawnmower, was out trimming their gravel as I tried to drive by.
