yea, the 100 bucks shipping sucks... so just factor that in with what deal you are getting. I got my 99 cobra front from bumpers.com for 169.00 pre painted black
but they dont do that anymore.. lol
your grill will work fine, you seem to have a mach 1 grill delete, so the new bumper will just bolt right up, the little mach 1 front peice will not be re used of course.
as long as you have the correct radiator cover peice (what the hrose bolts though that covers the grill area up) you are good. Not all grill delete kits come with the right parts, the wrong part leaves a gap at the top hood line that you can see the crap behind it from the front of the car, you can see the hood latch and all that.
