The rims are off a Mercury Sable. Maybe a centre cap from a Taurus between 1996 and 1999 might work - some of the rims were the same between the two makes just with different Ford/Mercury badging.
As for TPMS, I bit the bullet and had them put in. The upfront cost is a pain, but spread out over a few years isn't so bad.
