73LCA on 72 kframe

Hi i have a 72 dart swinger, And I needed new LCA for my car because my old ones were literally cracked.. and i got some 73 LCA for really cheap! I noticed that these had sway bar “brackets” on them. I was wondering if there is a way to mount a aftermarket swaybar on my original 72 kframe with these 73 LCA?
I read that the brackets change place between 72 and 73 on the LCA and that also the k frame change where the swaybar mounts? Is this an issue? Or does a 73 style swaybar bolt on with just a few mods Or do I need to do some serious fabrication on anything?
Or is this just a stupid idea?

sorry for my bad English..
greetings from Sweden!
