The Front Bumper Is Tied In To Both Of Your Front Fenders...
You Will Have To Remove The Inner Fender Wells To Get To The Two Long Bolts On Either Side....Once You Have Done This, Looking Up And To The Front Of The Inner Fender Well Where The Bumper Cover And The Fender Meet You Will See The Two Long Bolts...Remove These Bolts, Remove The Headlights, Remove The Grill And Then You Will See Two Or Four Push-Pins Underneath Where The Grill Used To Be. Pop Those Out, Then Remove The Two Long Bolts From The Other Side After Removing That Inner Fender Well...Once All Of This is Done You May Remove The Front Bumper. Now You Can Remove The Body Bolts That Hold The Fender On!!! As For The Rear Bumper I Believe You Have to At Least Drop Down The Rear Portion Of THe Exhaust to Get To The Two Bolts (One On Either Side) That Hold The Bumper On. For This Process You May Want To Have A Buddy In TOW To Help With Removal.
Also, As For This Part, I Believe There Is A "How-To" On Fixing Bumper-Sag For The SVT's That Shows Pics Of The Two Bolts That Hold On The Rear Bumper...Look In The How-To Area On The Main Page.

I Am Pretty Sure The SE Rear Bumper Uses The Same Bolt/Bracket Combo....
