I bought mine from a couple different Amazon links.
I will say though, if the seller sends it to you folded, it will be a pain in the ass to line up correctly. When I bought my first pair of "SILVERADO" to replace the chrome fender ones, I screwed up on the first one, but the second one came out looking good. That seller sent it in a flat package where they did NOT fold it.
I should've bought it again but my dumb ass went and bought it from another seller to reattempt the first side and it came folded. That was a pain to line up correctly. Had to bust out the painters tape and lay down a "+" cuz it would've gone on misaligned (the foam template came bent and folded).
