should there be a resistance across gauge elements ?
just for fun I thought I'd check this before installing.
I get a minor resistance on the TEMP gauge... about 150 ohms. the PRESS side appears open. this gauge is from a '71. is this normal ? I have a similar gauge from '75 that behaves in the same way and another from '79 that gives a resistance on both elements. input appreciated

Sent you a PM as well, but figured I'd post here also. Use your meter, set to ohms, and measure G to ground and G to 12V. You should have a resistance on both. However, the easiest way to test these gauges is to connect 12V and ground then use a little jumper wire connected to ground and touch it to the G terminal. When G is grounded the meter should be pegged all the way up.
