Not sure I am reading it correct or not, but,,,,
If he has cut any part of the OEM grill then I would say it will be difficult at best to get the true value for it.
That said, someone on ebay will buy it as they will find a way to mount it. People are very smart when it comes to saving them money..
Here are the grills that are available for the 04 F-150,Heritage, XL and XLT, painted surround, bar style center
Heritage, XL and XLT, chrome surround
Heritage, XL and XLT, painted surround, honeycomb style center
Heritage, Lightning, lower (bumper cover mtd)
Heritage, Lightning, upper
exc. Heritage; upper; chrome surround; bar style center
exc. Heritage; upper; chrome surround; honeycomb style center
exc. Heritage; upper; painted surround, bar style center
exc. Heritage; upper; painted surround, honeycomb style center
exc. Heritage; lower \
I looked up the Heritage, XL and XLT, painted surround, honeycomb style center to get the going rate price on a grill. It is going for 50 to 75 on the low end and has them listed as high as 200.
Hope this helps...
