KK is a 4:10 posi rearend code for a 1966-67-68-1969 Chevelle.(Except COPO)
CKK is a 4:10 posi rearend code for a 1970 L78 Chevelle only.
CRW is a 4:10 posi rearend code for a 1970 LS6 Chevelle only.
CRR is the engine stamped code for a 1970 LS6 Auto trans. Chevelle.

Transmission type did not play a part in rearend codes.
