I'm looking for an open element air filter for my 1982 V6 3.8L 231cid El Camino, everything I have found has a circular base but my carburetor has a weird semi-circle/trapezoid shape. I believe it is the stock carb but I'm not 100% sure. Here are some pictures of the carb. Any help is appreciated, Thanks!
(not quite sure how to add photos so hopefully one of these works)
