In their infinite wisdom the previous owner of my Zed has sawn off the threaded part of my gear shaft to make it a shorter throw meaning that now an OEM knob won't stay on without glue, blu-tac or anything else I can get in there to keep it secure - and nothing works, there is play in the knob.
Is this a massive job to replace the shaft? Where can I get one? Are short-shifter kits worth considering?
