I have a pair of NIB Hamburg-Technic front strut mounts, part #3133 1139 452 for e30 and others. the stock bearings were pressed out and new VXB bearings were pressed in. These have the correct 15mm ID for the KYB MR2 strut inserts if you are shortening your struts. Never used or mounted as I scraped together and went with Ground Control mounts instead. Don't grind your shock shafts- do it right the first time and get these. $75 plus $15 shipping anywhere to the lower 48.
