How to identify a 67 specific k-member

Looks to have 1 mount on the passenger side. So it's a 67 dang
Only thing thats different is the idler arm. 67 1 year only k frame because of idler arm and mount. Here is pix of 67 K frame i am modding to the 68-76 style idler arm mount. You can see the old mount attached in first pic.

There’s several bastard parts on 67 A bodies. The idler arm is different and maybe the pitman.
