Dead Fuel Sending Unit

[XSongwrtr@xxxx]

Does anyone on the list have a dead fuel sending unit for sale, cheap?
The reason I want one is to try some expermentation with a Bosch unit 
I found in a humpback Saab. I need to compare the resistance 
readings, float values, and measure float movement etc. to try and 
compare the differences between the 2 units.
If I can't make this work, I'll pop for the Tankzilla, but I want to 
try. (I fried mine testing it with a battery charger).

Thanks,
