The one out of the 69 Super Bee is actually the 70 thru sway bar style. BUT I have heard some documented 69's got the new 70 type K-members. I think they still have the 69 type sway bar that bolt to the front lip of the K-member.

The black one on top look like a 68-69 B-body. You would have to measure the bolt spacing and see if it has the 68 and up thru bolt idler arm mount.
