When I got my '96 (back in January) it had a damaged l/h end cap - one of the reasons I manage to knock the p.o. down £150 (about, $175, at the time) It now seems my original assessment was right & I have to remove the whole bumper BUT that also means I'l have to do the same to any wreck that I might find (so far, only 2 - right colour, wrong year!).
The bumper also has a small (egg sized?) dent & a few (primer deep) scratches in it, so maybe the answer's to replace the whole lot! Mind you finding one's another matter, even at a premium price from a specialist dismantler.
An alternative is to leave this 'til next year when, with any luck, I'll be Stateside for a couple of weeks in May - so if anyone's got a good l/h end cap, preferably in dark green, within, say, 500 miles of Phoenix, Az (any excuse to go off on a little road trip - even in a rental car!) let me know -& hang onto it.
