1972 318 LA Timing Tab (Austalian Chrysler)

Hi All,

I have a '56 Desoto Diplomat that has been repowered with an Australian origin 1972 318 V8 (LA motor) from an Aussie VH Valiant.

This particular engine has a bolt on timing tab on the left side of the motor (looking at the front of the engine). The tab is missing.

The water pump hose points to the right side of the engine. The balancer and timing mark is on the left. There are no marks on the timing cover, hence my assumption it is one of the bolt on tab engines.

I am hoping someone can tell me where to source one please.

Example below from an older 273 engine.
