It almost looks like a 200x front end to me, but not 100%. If it really is, and that key switch belongs on there, you may have an 87 200x front end if your lucky. If that really is the correct switch, you just struck GOLD! I have seen them bring big bucks, like 400 bux! Good luck, and if it is one, you are a lucky son of a gun.
