You can get a whole set of OEM Expedition aluminum wheels for $25 a wheel at the local pull-a-part, of which we have 3 in the Atlanta metro area, Plenty of styles to choose from, if not that specific style that would fit your truck every time I go there. Maybe you have some pick and pulls in Orlando area also.
I haven't had any opportunity to check our boneyards here in a while. The last time I did I was rather frustrated finding parts for a Plymouth/Chrysler mini van which should have been an easy task. I am just hoping for someone who has a pair in their garage so I don't have to slog around in the mud with a tire jack.
