Original right hand (RH) dash stereo speaker taken off a 1970 Monte Carlo. I know its compatible for 1970-1972 Monte Carlo and Chevelle models as well but possibly more. Its around 6"x4" in size. This specific speaker does still work. The front fabric is still in fairly good shape there is no rips through it and its all still attached. Still has the original plug. The frame is also still in really good shape. (Last two pictures are just to show measurements and is not the speaker shown on the listing)
