Hello from Greenville, SC. Just recently purchased 1999 Expedition. Took a couple of weeks to clean and detail and now it looks pretty good. Car has 141,000 miles and most everything works. First trip out of town blew plug 100 miles from home. 1,800.00 bucks later everything seems fine. I do, however, have a couple of questions. # 1. I am missing the 2 real wheel caps. Is there a parts for sale section on the forum or does anyone have a source for these caps? They just snap into wheel
. #2. Do any of the current floor mats, similar to Weather Tech fit my 1999 model?

 

Here is the for sale section of this forum

I would just look in EBay for the hub caps you need, if you dislike buying on the internet you could try your local junk yard.
For floor mats no idea what the 99 expedition floor mats look like, you could just buy generic ones that with a little trimming will fit very well.
