| This listing is for a single rubber/metal washer for the lower end of the differential support bar otherwise known as the moustache bar. The lower washer has a 12 mm hole in the center. The upper and lower washers are not interchangeable. Requires 2 per car. To complete this job, you usually need to replace the bar end bushings as well as the upper and lower washers. See listings.
