None I don't think... Unless you modify the mount flange that you will be using... I don't recall 52s being used in MirrorBeams, just 500s... But I may be mistaken...
52 series light modules were definitely used in the original generation mirror beam housings before the 500 series came along and replaced them. I speak from experience because I had a pair on my '03 Crown Vic.
