What's wrong with this K member?

I can't see the mount towers on the frame well enough to see if anything was changed. I can see the spacers that are moving the motor forward.
I have a couple 68-72 K-frames BUT if you go back to that you will also need the 68-72 center link, idler arm and steering arm. You can use the 73 lower control arms but not the sway bar.
Will also need the 67-72 motor mounting brackets, biscuit style.
Can use your upper control arms, spindles and brakes.
Probably not what you wanted to hear
