1974 350 in head sending units
I recently had my heads done and they came back without the sending units. I believe the one on the drivers side was for the coolant temperature. I don't know what the passenger side one was. Any help? Thanks, Tom.

The '74 AIM should show what sending units went into the heads. Or you can check details in one of the C3 aftermarket parts catalogs.

I'd go back to the shop and demand that they find and return both your senders. 
It's very difficult to get replacement units that have the correct resistance.
The drivers side sender is for coolant temp indication, the passenger is is for the TCS emissions equipment.

I'd bet the shop 'stooge' pulled them out with his trusty vise-grips and pitched them....
