it's pretty much what old boy said in his post...

remove the bumpers and side skirts and test fit everything sanding as you go...

 

ok now i have the front and rear bumpers on. Now i need some tips for putting on the side skirts which i will be putting on tomorrow because it was getting to late to finish them today. thanx

 

That I am going to do, since the side skirts fit perfectly, is im gonna take off the stock ones, and in gonns double sided tape them to the aftermarket skirts. Snap them all back into place, and screw into the wheel wells. that way, it takes a couple minutes to take off, if I ever need to.

 

undo the front fender lining where it attaches to the stock skirt. then slip the skirt over the factory one. you may need to undo the factory clips to slip it on. once its on, put the factory screws back in. use some sheet metal screws and screw the ends of the skirt into the factory one. my shop used screws to screw the top of the skirt into the factory one. some ppl use double sided tape. its up to u

 

i just put the skirts onn. i had to take the stock ones off because the black widow sides wouldnt fit over the stocks.
