VS Commodore Boot Gas struts fit perfectly in existing mounts with existing brackets. I had a couple of banged up original struts , so I drilled out the rivets to remove the brackets.

The big down side with the VS boot struts is that they do not lift the tailgate up to full extension - but this suits me at the moment until I find some good originals. Just have to watch my noggin.

I like Karls' modification but would add a strengthening plate to the mod.
My local strut guy has modification plates - in chrome or black - for those who want to add some strength to the lower mounting point.

Cheers,

Peter
