carbon fiber fender flares

[TickleTimeTim]

picked these off a guy with an xb, i would like to make the rear ones work too, but we will see if i can make it happen. they are rivet less, so i guess i need to fill up the back with that seaform concrete stuff, and then 3m? if you have suggestions, please let me know. i figured the small part of the rear fender that shows under the flare, i could cover in the vinyl carbon fiber so its not so obvious. its hard to see unless squatting down anyway. please tel me what you think. Figured they were worth the $50 i paid for them. now i just need spacers.
