I have three pairs of spindle nuts that fit the early 911 struts with 3" caliper bolt spacing. The are actually from 70's Mercedes-Benz cars. The shape is a little different but they fit fine. I lost a pair of OEM Porsche spindle nuts I had for a set of struts and found the Porsche PET program and Pelican show the wrong part for the spindle nut for the early struts. They show the same part number as is used on 914 struts. These are the same diameter as the 914 spindle nuts but have the fine thread. $15 a pair shipped.
