Note 1.  There are two distributor shafts found in 43D4 and 45D4 distributors.  The more common shaft has a longer points cam than the relatively rare shaft with a short cam.  Remove the rotor and measure the distance from the top of the distributor shaft to the top of the points cam.  A dimension of about .420" indicates the shaft with the longer points cam.  Distributors with this shaft will take the Ignitors indicated in the table above.  A dimension of about .525" indicates the short points cam.  The Ignitors will not work in distributors with this shaft.

For other MG applications, compare your distributor number with the list on the Lucas distributor page.  Click here for Lucas Distributor Applications.
