This is a pair of new factory inner fender wells for 1970 / 1971 and 1972 Monte Carlo models. These inner fender wells are reproduced for Monte Carlo only NOT Chevelle like some people are selling. Monte Carlo fender wells are similar to Chevelle, but they are longer in the rear and have a different contour on the wheel lip, among other things that are different. They are black ABS plastic. You will need to buy a-frame seals and you must order ones for a Monte Carlo and not Chevelle as they are different.
