Front inside wheel well

[z24forlife]

hello everyone... well here its a nasty winter and i hit my front end on some hard snow... so now my bottom spoiler is hanging... the thing is the part thats screwed onto the inside wheel wall.. well part of the black plastic in the wheel wall cracked.. and so i need to replace the inside wheel wall. i need to know how do i remove the inside wheel wall's black plastic on passenger side?? Is it one piece or two pieces. Plus those small kinda clips are cracked aswell... now like i did last year... i screwed that end spoiler onto the bumper with stainless steel screws..... off course im gonna have to put some all around now seeing those clips have broken off. So yeah could anyone explain to me how to remove that part of the inside wheel wall... has anyone got diagrams on how too. Thanks in advance...
