Hi - I have just acquired a Vectra C 1.8 VVt 2007 and have some broken parts to replace.

1 The left hand heater knob has it's black cover missing. The body of the knob is still OK - it's clear plastic with a light inside it. Can I replace just the black cover or the whole knob ? How ?

2 The driver's door lock "pull" is missing. There is threaded rod sticking up - will a new pull just push on ?

Any suggestions ?
