will 67' K member fit in a 66 dart?

Just wondering, I 'm rebuilding the suspension on my 66' dart GT, and going to 10" brakes. Does the 67' K member fit in the 66? my 67' parts car has a completely new suspension, and It appears the rear end housing and springs Interchange to me, as my 67' parts car has the rear end in better condition, and 10" brakes as well. They are both slant six so I'm good there.
