My 75 SIII had the compliance plate on the radiator support panel. Post a pic of the engine mounts - that;s the easist way to determine what engine it started with, although it's highly probable that it was the LR 6 cyl. Stay with the holden conversion - better performance, less hassles. Might be an idea to try posting up your chassis ID, or looking at various sites that ID via chassis numbers ( Look at the VIN numbers post and the CALVIN website) - don't be surprised if it turns out to be a little older, as the lack of standard vacuum booster sounds a bit weird. I'm sure others will have more to say on the topic
