So when I brought my XJ the previous owner removed all the emblems. I ordered new ones but I have no idea of where the exact placement (measurement wise) I know the general location. I tried to google search and forum search but found nothing. Any help would be greatly appreciated.

Oh I have the front and rear Jeep badge, the rear 4 liter badge, 4x4 badge left and right, and the cherokee badge left and right.

 

Google images are everywhere. I found them searching for '2000 cherokee XJ'. I do not see exact measurements, but you can get pretty close just eyeballing them.

 

Personally, I would just be eyeballing it as well. its not like your trying to restore a '69 Camaro SS to original shape, I mean, unless you're OCD about it, or are trying to get it as perfect as possible because your XJ is in showroom shape...
Heck, I'm pretty sure the PO of my XJ replaced the front fender "Sport" emblems and its the wrong ones... they just dont look right to me for some reason, but not bad enough I've tried to figure out what and here they should be, I've never google imaged them to find out. I guess I could do that now....
