I would just buy a generic gm coil and hook it up to see if it works. And then you'd have a spare.

If you have an 6A box its pretty simple to test the coil. Connect the coil to the coil wires on the box, get power and grounds to the box, hook a spark plug wire or similar to the coil output, and then short the two magnet pickup wires together. By shorting those out the box will trigger and fire off the coil.
