Use a resistor.
From another website:
Does the AM sensor come with an predetermined resistor?
From another website:
One could use a 1k Ohm potentiometer to dial in required resistor value. (VERY IMPORTANT) Set the potentiometer to the HIGHEST value. (VERY IMPORTANT) Put the pot in series with the meter and the voltage source. Turn the potentiometer down very very slowly till the voltage across the voltmeter is at 5v. Turn off the circuit. Isolate the potentiometer and use an Ohm meter to determine the resistance (Ohms). Now use the resistor and confirm final voltage.

Use the LM317 ( from RadioShack) as suggested and it will always be 5V.

What Dan said. ^^^^
If you want to build a dedicated device, you can use a LM7805 regulator with a couple small caps and a heat sink to get exactly 5 Volts. Radio Shack parts for a few dollars. One Amp current capacity.

If yer lousy at fab, this is what I'd do. The PS might fit in the glove box, for stealth:
