Bumper swap / trim Qs

[Ian NFLD]

Ive got an 02 525, silver with painted to match exterior moldings. I picked up a used M5 front bumper that I'm putting on and want to switch to black molding for contrast. Front and side trim is easy swap with m5 stuff, but what about the rear? I gather the black center trim piece from the m sport wii fit my stock rear bumper, but what about the two side pieces? Real oem only lists painted pieces for the 02. Do the black m sport pieces fit? What about the pre-facelift pieces?

Thanks!
