Is it possible that a 1973 A body K member

So the 73 k frame can be used on a 1970 with all 1970 parts except motor mounts ?
Center link pitman arm and all the rest from 1970 will work , what about the 1970 style sway bar ?
Just wondering why my parts 1970 H-340 Dart has a 73 K-frame as it is an original 340 v-8 car .

Yes, the naked K-Frame can be used with as long as you use all the pre 73 parts if you have a sway bar. If you have no sway bar then the LCAs are the same and can remain on the 73 up K-Frame.

Does you K-Frame have the washer welded to the front of it?
