You are bidding on one rocker panel, either the left or the right side, for all 1956 1957 Chevrolet two door cars. Ask about $$$ discount. These panels are die stamped right here in the USA by American workers from good old American cold rolled sheet metal 19 gauge, nothing at all like the foreign made current reproductions sold elsewhere on E-bay . The rockers that you see pictures of on other auctions with the dull silverish color are bent up on a sheet metal brake from 22 guage metal with a galvanized coating on it that gives off poisonous fumes when welding it. If my rockers have any surface rust beyond what will clean up with metal conditioner I have them cleaned by the friendly folks at Restoration Specialists in Hales Corners WI. With their alkaline electrolytic immersion process they can take any size metal panel up to an entire car body and clean all the paint and rust from it so it looks like new sheetmetal again. I have thousands of these body repair panels for cars and trucks from the 1940's, 1950's and early 1960's so if there is anything you are looking for just let me know and I will put it up for auction next. I will always try to combine panels for shipment if you are purchasing more than one item. If you ever read Hemmings magazine take a look for my ads under the name Rocker King, you will see that I have been selling panels via ads in their publication for the past 35 years.
