Column Differnces - 1970 Duster

With the lock out, if not doing a resto, wire the lockout to the open position so the key can be removed.

The real difference in the 70 and 71 column is the 71+ has a thumb release lever that needs to be depressed to remove your key. Other than that, it should be a direct swap after verifying the wires.
