I bought a Z Cars kit from the old company and had the wrong drive shafts delivered. New ones were sent out. I fell ill during the build and then the company went into liquidation. I am now back to building again but one drive shaft still appears to be the wrong length. Does anyone know the origin of the driveshafts supplied with the kit? It's a Yamaha R1 engine with Quaife diff. The photo shows the problem I hope.
