I found nothing usable in wrecking yards, and the new OEM part is just ridiculously expensive at Aussie $420 (USD230). I still wanted proper bonnet insulation rather than putting sagging and potentially deteriorating untested material in the engine bay. The workaround I found in Australia is the relatively flat insulation of the VN Commodore, costing A$57 new plus A$1.40 each for the plastic clips. I decided against the standard Holden clips, as they are not removable. The ones used are held in place by a separate plastic screw that spreads the feet.
Marking the new holes on the insulation was done by inserting the clip bases in the holes of the bonnet and sticking into the screw holes bits of bamboo satay sticks. These come through when the insulation is pushed against the metal, clearly showing the hole positions. The rest is easy.
The insulation is somewhat smaller than the Volvo bonnet, but works well – good return to little effort. High frequency noise such as the swishing-squealing sound of the belts has been cut out. Low growl remains that will require cabin insulation.
