I bought a set of "oem Mopar" replacement fog lights for my 96 Indy on ebay. I had 2 issues. For one, the plastic lenses did not hold up very well. My original ones were plastic, but did not crack no where near as bad as the replacement ones did.
The other issue was the bracket. The angle was wrong. It angled my lights up way too much.
I ended up buying a real nice set of Pilot brand lights. The brackets are different but they fit the OEM location opening.
