Rheostat Sources???

After dealing with fuel gauges, temp gauges, and oil pressure senders, I decided it's time to make up a tester for those circuits. Depending on year, the senders range from 0 to 105 ohms or 0 to 88 ohms for the range of the instrument.

Went to Radio Shack today looking for a 0 - 100 ohm rheostat, and all they have is 0 - 25 ohm. That would only cover about 1/4 to 1/3 of the range of the gauge, so not very useful. Does anyone know of an electronics parts source where I can buy a rotary rheostat with a range of 0 - 100 ohms?

Also need a source for a knob to put on the shaft. Radio Shack doesn't seem to carry that stuff any more.
 
There is a store out in california called HSC they have everything, apparently even a website but the address is not with me right now. Finding a pot that fits the specs you need can be turned into a rheostat.
