Lemme check my stash at home. I think you are missing the breaker bar and the mid length extension? Not positive. Is there a set # anywhere on the box? Usually they were just paper tags.
I have the correct breaker bar with <SK> logo and in like new condition. Also have two correct style sockets, both are 8 point square sockets, one is 1/4 and the other is 3/8. Can ship all three to you for $12
