I recently acquired a nearly pristine 2006/07 XJ8 that has Growler emblem on the hood. As far as I can tell this can be replaced with a Leaper, if I can find the right one. There are many on line, but some may seem to need a second screw attachment. Some are spring mounted. I may be able to get one from Manhattan Jaguar, but just want to know what's best for the car and how difficult is it to install?
