I put an XE Front end on an 87 XF GL I had.....It all bolted up fine with no mods needed (not that I noticed at the time anyways)
Only thing was I needed the steel bumperettes (the two bits the front bar mounts to) aswell as the front bar so that the grille was able to be mounted properly
With the Headlights, it was just a matter of cutting of the XE plug on the light (or XF plug on the loom) and replacing with the XF plug (or XE plug if you cut the loom)........All the wire colours were matching
