just purchased a rear black rubber spoiler for my 85 635csi from Allens bimmer in Wilmington CA. Allens indicated that spoiler came off a 633. Made by Foha in Austria w/stamp date of june 82. Production style is Heck and type #1216.All info from underside of spoiler. Question: Is this spoiler also aftermarket for my 85 635csi? When placed on rear trunk lid it has about 1" distance from trunk edge on both sides. also has roundel badge cutout. otherwise spoiler looks good but i dont really want to bolt on if it is not really for my 635. Any feedback will be appreciated, thanx
