I did a parts locator search and availability. Seems like no one has them anywhere, so unless you want to change colors your pretty much stuck with what you have.
Babbit's onlne has Red (2016) panels for:
Front Door: $14.31/side
Rear Door: $65.43/side
Bed Panel: L/$.500 R/$3.75
Hood: $50.80
Front Fender: $113.23
$332.26 for all plus whatever they charge for shipping.
Other colors (except Camo or LE painted panels) should be similar in price.
