Pizzi348, the bonnet number is stamped on the outside lip on the side somewhere, as is the boot lid, as are the shrouds somewhere, and behind the cockpit trim to name a few places, I dont think it was a best fit reason, more a case of car assembly identification, I can trawl thru some of my assembly pics and hopefully find some more specific locations, had to scratch a lot of paint off to find them in the first place!, if they are replacement panels then they will probably not be numbered
