Just to expand on his comment...
In the Group Buy Section, there is currently a GB for a Pre-98 SVT Bumper. These have to be custom-made to fit on a Pre-98.
Any stock SVT SideSkirts and Rear Bumper will fit on a Pre-98.
Just to give you a heads up, we're not talking cheap here. The Front is $450, the sides run almost $200 and a rear will run about $400. And then painting would double that.
