I have an 89 M3, with ellipsoids. I was planning on replacing the ellipsoid low beams and high beams with a set of higher quality CIBIE sealed beams. I just discovered however, that the ellipsoids have a special mounting bracket that they screw onto, and that the CIBIE sealed beams will not work with this bracket. Is there any way I can purchase the sealed beam bracket and use it in place of the ellipsoid bracket? Will it fit? Also, will the bracket for the sealed beams accept any sealed beam light as long as it is the right size? Most importantly, what are the part numbers for the sealed beam brackets? Thanks in advance.
