Ill send you the template to make one for $12, then you can make one yourself, if you wan pics Ill send them to you but its really easy with a jigsaw or plasma and can be done with snips if needed...
here is a link to the one I got. Real nice it has BUICK MOTORSPORTS engraved on it and you can get the part to replace the upper section of the heater box so you can reinstall your hood weatherstrip.. http://www.buickgn.com/ACcowlpanel.htm
