timing chain replacement

Clifford and Offie both have the same bolt pattern on the manifold itself (if I remember right). The Offie adapter will only fit one way. On the Clifford adapter the holes used to mount the adapter to the manifold are "slotted", slightly, at an angle. This allows the adapter to be mounted in any position.

well i remember it has two sets of mounts on the carb flange but i think you are correct in the slots for the adapter to intake...
