Found a pair of old front suspension bottom trunnion bolts and spacers which are the perfect size to extend the drop links. Hunt's Eighth Rule: "If you haven't found a use for something yet you haven't kept it long enough".
No going back now.
Ready for welding, showing how the spacer can be used to sleeve both welds for additional strength.
Detail of cut and shaped ends to be filled with weld.
Welded and flattened ready for repainting.
Ready to fit, I decided to rely on my welding for a neater result. However shortly after fitting one of the welds did break, so I did fit a sleeve when repairing that. The other sleeved one has been fine ... so far.
