The rear fenders may end up being another application customized by you. Since you would be changing all four corners you have more options as long as they all compliment eachother. It could be a cool project.
I have done ground kits like that before and they always make me think i should have just made them out of metal myself. Then i remind myself that I'm so picky it could take me months to fab up something like that.
I Love a challenge and sometimes think I could be as good as the metal fabers on tv shows like Bitchen Rides and Texas Metal. Then I remind myself I'm a custom woodworker. lol
I am a Hobby Faber who was a heavy Collision Tech For quite a few years so sheet metal and frame structures dont intimidate me but I am out of that business.
I wish you Luck and Lots of Fun which ever way you go!
