How much for a right rear wheel well oem fender flare?

[Mr. I - Man]

Some jackass in a gravel hauler I guess didnt think it was important to check his rear dualleys for rocks stuck in them before getting on the road. So orange size rock comes flying out I swerved to miss it but it caught me right under the Rt passenger chipped up the paint and damn near ripped off the plastic trim. Any ideas on much this piece costs? God I hate dirt bag truck drivers.
