Flathead temp. senders

Changing flathead to 12 volts, anyone sell temperature senders in 12 volt for both heads or do you have to use a voltage drop?

 

Use a voltage drop, Oreilly's has a 64 Mustang voltage regulator for the gauges, easy to install, works great.

 

The gauge is voltage sensitive not the senders. look at chevy,fordman's post.
Connect 12V to the regulator and 6V to your gauges.
