Just done one myself so i can help yer out a bit me thinks..
FIXING TOP:
Valance just slips over the existing frame of the car,be carefull you dont split the sides when you get to that stage..try to do it at least as poss..once to see if it looks ok then while it there,mark where the clips will go for the top part..your see what i mean when you look closely at the inside top of the valance..you can see there are roughly 5-6 etched out spacers which house the clips..get a marker and place a mark on yer car where these clips will 'hit' and there about 10mm in from the edge if i remember correctly....take the valanc eoff again and drill yer holes..get some rust prevention primer..(hamerite) and give yer holes a lil spray..youve just drilled and exposed bare metal so its worth it.next time you touch the valance your fix it permently,this way youve handled it as least as poss to protect yer sides..
once youve got clips fix them to yer valance ready to find yer pre drilled holes..they just find there own way and you hammer down the rivet in the middle of em once in place and there fixed..
FIXING BOTTOM:
make sure youve got ALL the original clips off from underneath yer car where yer old splitter was..there white clips located approx 5 times along the underside/front of the car....from the stealers diagram your see that the bottom is held by lil black rivets...these push through brackets located on the bottom of the valance and these in turn find the holes that are originaly there and DID hold the clips in that you broke off earlier..
