We got this at a swap meet about 20 years ago and I have no idea what it is. I believe we were told it was for a B-body by some dude on Reddit, however not really an authority. In any case I need to know what it is so I can sell it to someone who needs it and get it out of my garage. Any help would be greatly appreciated.

There is another data plate screwed to the front but I cant really read it other than it starts with a 7.
