Are the middle pieces on the rear-end of the Crown Vic compatible w/ that of the MGM?

[LieutenantCracker]

Sorry for all o' the postings I've been putting-up lately... I've had some down time tehrefore, more time to work on the car(!)

As I said in my last post, I recently replaced both of the broken tail light housings on my 1999 MGM w/ those of a Crown Vic', and it just looks kind of weird now b/c I didn't replace the plastic reflector-piece on the trunk lid center too.

I don't want to buy one off a CV, if I'm not absolutely certain that it'll fit b/c the junk yards' warrany doesn't apply to that sort of thing.
Does anybody know about this or where I can get this info? I don't go to the dealers anymore b/c the Parts/Repair Dep'ts employees are usually pretty busy, and ALWAYS asses, when I come-in w/ questions, or even when I'm trying to buy something!
