Thats what I was worried about since this is a slant 6 car and I thought all after 73 were disc brakes and bbp wheels. I didnt know you could still get drum brakes. Thanks for the update.
Score!! I got the control arms yesterday and just cleaned them up. Bushings and ball joints are all new. Looks like they were just replaced . pull apart yard charged 19.99 each. NICE!
