Garth mine is 05 and is exactly the same as yours, will hold it fine but wont lift it without assistance. While it manages to lift it without it falling down on my head I will be happy but if your adding sound proofing then I guess it might give up the ghost!
Interested to know why your adding sound proofing, have you modified the engine making it louder? as mine is as quiet as I would want at motorway speeds (I can hear other peoples cars more than my own) and I like the occasional turbo noise.
