That looks to be a modified ARB 'Sahara' bar. Check it out at the ARB website (www.arb.com.au), they do not list that they are available for the Jackaroo but I'll have a chat to the ARB guys here in Brisbane and see if there are any plans to do it.

The V8 is the same as in the HSV Clubsport here, the reguar Commodore only gets 235kw, the HSV Clubsport get 255kw and the HSV GTS gets the 300kw version that is the same, I believe, as what the Pontiac GTO will ship with.

I enquired about getting a motor and inserting into my Frontera (Rodeo) and Holden believed it wouldn't be too difficult.... Cost was about 10k Aus for motor, computer and box. This Holden version just makes me all the more keen to hack my Frontera up... maybe Holden will sell that car???
