A while back someone posted looking for a speaker box for a f100.  It looked like the one I took off my 56 that was mounted near the rear-view mirror. 
Anyway, if that was you, PM me and we can figure something out, I'm not trying to get rich, the price would mostly just reflect the cost of shipping from 95350.  I'd say the condition is pretty good,  no big dents or other damage but a good cleaning is in order.  Let me know and I'll get you a couple of pics.
