Title says it! Have converted an 89 Horizon to 5 lug, ventilated discs in front and want to do the same to an 88 Horizon. Anyone parting out a GLH or GLHS or have a spare set of knuckles laying around.
THESE ARE NOT THE SAME AS ORDINARY OMNI/HORIZON KNUCKLES. They are thicker so the bearing hole can be deeper to use the same bearing as the heavier cars and the bolt center spacing for the brake horns is different.
