i scored some 7" headlights out of a 5 series, and i want to hook them up..

around the original lights there are white plastic clips holding them in with the adjuster screws.

is there a way to remove old units w/o breaking 17yr old clips, or so i soak my new headlights in some sort of solvent, to loosen up the glue holding them together - and then use a sealer to attach new lenses to old reflector units?

by the look of things the new headlights will fit the white clips - im just paranoid about breaking them - unsure of the best way to attack this
