Not sure on the turnaround times (I got lucky and was able to stop in on my way through town and picked up a "scratch and dent")
However, you will LOVE it when it does show up. Hopefully you have the newer style factory bumper mounts so it will just bolt right up. My '96 needed plates welded on the front frame rails, but totally worth it.
edit: I see you have a 96 Limited...crawl under and see if you have these crush cans on the front frame rails instead of a flange with 3 bolts.
If so, make sure they send you these weld plates.
