Well eventually, some time after mid 1979, Holden moved with the time's, and started identifying part's with the names most commonly used.. I experienced an issue with part names about six months after I bought my ute in 79. I lowered my ute so it didn't look & handle like a 40 series landcruiser at the time.

I had finished doing a service and was reversing off the ramp's, unfortunately I came down too quick and the spoiler caught the edge of the ramp and cracked in three places. So back to the selling dealer to make some enquiries about a replacement. I asked the gentleman about a new front spoiler, I had to explain to him the part required, and point it out in the parts manual. It was then known as an "Air Dam."

Today these part's are known as spoiler's, the language all understand. I could never grasp why Holden referred to them in a text book term, when they were aiming a product squarely at the youth market. My spoiler ended up being welded, and looked brand new again for the price of two dozen can's of tooheys draught.
