Chrysler C-4166 Tester

It actually should look like this..Vintage-Chrysler-Ignition-tester-C-4166.jpg

There should also maybe an adapter for the 5 to 4 pin ECU?

Even better if it's a 4166A

If you have one, price?

What's happened is my duster died a couple weeks ago, lost spark. Been throwing parts at it with no luck.
