My father-In-Law has a a 7AL-2 part # 42626, which comes with a MSD Coil Pro Power. I looked on the Web site for info, but all I found was the 7AL-2 Plus, which is probably a updated version. This box was serviced By MSD years ago, but has been self ed since then.

So here is a few questions.
I assume this is the correct coil for this box? Can this box be run on the street? I don't think so, but maybe with a different compatible coil?

Are these boxes dependable, and reliable?

Thanks
