yorkshire_spam Posted June 1, 2017 Share Posted June 1, 2017 Anyone know what thread the top ball joints on the spitfire etc are?From my measurements it looks like the ones I have are M12x1.25 ? Does that sound right? That doesn't seem to fit with the spanner size - I thought I used 5/8" AF - making it 7/16UNF but that seems to small.I think I'm confusing myself and should take a rest!

yorkshire_spam Posted June 1, 2017 Author Share Posted June 1, 2017 Just to follow up... part number is (I think) GHF224 - 7/16 UNF @ 5/8" AF. 🤔 Quote Link to comment Share on other sites More sharing options...
yorkshire_spam Posted June 1, 2017 Author Share Posted June 1, 2017 And to confuse me even further... 7/16 UNF fits great on the 2 ball joints on the Spitfire, but NOT the spare I had on the bench that I was measuring?! Sod it. Quote Link to comment Share on other sites More sharing options...
Richard B Posted June 1, 2017 Share Posted June 1, 2017 and to confuse you even more. Triumph used the larger T nut on 7/16"UNF which is 11/16" A/F The metric ones are after-market... Quote Link to comment Share on other sites More sharing options...
