This is probably an unusual upgrade but someone may benefit from this information. I have a '99 that came with 15" wheels. I upgraded to 16" wheels and larger (01-03) brakes. However, I still had a 15" spare until recently. The 15" wheel wouldn't clear the larger brakes so if I had a flat on the front, I would have had to swap around wheels until I could use the spare in the rear. Luckily, that didn't ever happen.
Recently I found an 01-03 getting parted out. I took all the spare tire stuff hoping that it would fit my '99. I found that it was really easy to do. The spare tire "tray" and the spacers/fasteners at the rear are needed but that's it. They fit just like factory. It was quite easy and I'm glad to not have to worry about the tire swapping I'd need to do if I got a front flat. :-)
