Little update, the koenigs were beyond repair and one had a flat spot so I sent them back. They will have another set in good condition soon so I'm waiting (again) for those to come through.
In the meantime I got a set of veilside andrews that we're leaking and needed a rebuild so I spent Xmas holidays stripping them, getting old sealant off, cleaning, resealing and rebuilding them.
Also bought a juran low seat rail and the drivers seat arrived today, all bolted straight in which was a relief.
Next is fitting a pair of origin 20mm front wings, getting repaired and painted over the next week or so.
