NOS chrome remote driver side rally rallye outside mirror duster dart sport

I have for sale a a chrome remote driver side rally mirror for a-body......I bought this advertised as a NOS piece but did not come in a box with a dealers name and part number on it......So I am unsure if it is NOS or a rechromed original...I am leaning toward a rechromed original but not sure...........the chrome is very nice....the head is a little loose on the base.....not sure if it can be tightened up or not?? The cables, gasket, and toggle look like new..........150.00 + shipping.....postal M.O. works for me.....located in Drums PA
