The 1998 and 1999 fobs were totally different. They didn't change to the switchblade type until 2000.Sadly, it doesn't fit. It won't click closed.
But the shipping was super fast!
At least ECS does have the earlier type that fits my switchblade. I ordered one from Ebay and I hat to cut the side on top in order for the key chain clip to fit. I may order me a couple of these along with other items so I don't have to pay that huge shipping fee for a 1/2 ounce key fob cover
