Voltage Regulator - electronic ignition

Hey guys,

Well today was the last day i took my project (68 Dart) out for a spin before she mostly hibernates for the winter. I figure over the winter months, i will work on electrical and some more body work.

I have a question regarding Voltage Regulators. I will be changing her over from points to electronic distributor and was told i have to change over my voltage regulator. The one in the car right now is just a black box with nothing written on it. A guy in my area was parting out his 68 Dart and gave me a regulator. It also is a black box but has "IGN" and "FLD" on it.

Is this the correct one for me to use? Is there any way to test it to make sure it works, or are these things bullet proof?

I attached pix of the regulator

Thanks in advance for any feedback
