Then look and you will see the OPTION codes that you had to order to get bucket seats in a Yenko Chevelle. It was just like a regular Malibu or SS car, standard seats were benches, you had to order the bucket seats as an OPTION. I hope anyone else who syas that you couldn't get bench seats in a Yenko gets the facts straight before saying anything else stupid.
