I haven't done a body kit on any of my cars, but I have helped friends.  My experience is that it takes a bit of customizing on everyone of them.  You can do it yourself and have it turn out great.  But you need to be able to make the adjustments.  If you don't think that body work is for you, take it in.

well im looking at it but i dont see what I would need to do to it. I dont mind doing fiber glass work if thats what it is. It seems like all I have to do is cut off the bottom portion of the rear bumper and find some way to make it stick to the rear add on.

mine's a 96, so that wont be affected.

I didnt get a full bumper. i got the bottom half of a bumper. I think I'll have to cut my bumper along the horizontal line and add the rear in place. Ill get some pictures
