73 a body k member in my 68 cuda

My 73 duster has a 68 barracuda K frame. I would think any a-body K member from 67 to 76 would be interchangeable? And that is question? For the masses...
And as I said above, yes, IF you swap the entire thing. There are a few pieces that are not interchangeable, for example, you cannot use the 68 upper control arms on a 73-76 spindle. You also can't without modification, run a 73 swap bar on a 68 K. So you can't mix and match, it's one or the other, but the entire thing is interchangeable
