Ian28 Posted August 23, 2021 Share Posted August 23, 2021 I appear to be missing one of the two small knurled thumb nuts that should hold the speedo in the dashboard. Does anybody know a good source for these? Or what size of thread is used? I hoped I might find it in the footwell but unfortunately not, maybe it got vacuumed by the previous owner after it presumably came loose and dropped off.... I'm sure I could find something usable in my box of bits but be nice to get the proper item Thanks Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted August 23, 2021 Member Share Posted August 23, 2021 I wouldn't assume it's the same thread on all instruments... ... but you can get them in several sizes here on Ebay.Jonathan Link to comment Share on other sites More sharing options...
Ian28 Posted August 23, 2021 Author Share Posted August 23, 2021 Yep thanks Jonathan I had seen those but wanted to be sure of the size and or metric/imperial, perhaps there is a nut expert on here...who will give the nutty answer Link to comment Share on other sites More sharing options...
