I have a 1982 308GTSi. Clock works great, except it's about an hour behind. However, the knob the re-set the clock is either stripped or not engaged, as turning it does nothing. Here are my questions... 1. Can just the clock lens be removed so I can re-set the clock? If so, how does it come off? 2. If I want to take the entire clock out, how does it remove? There are two small black screws in the dash area surrounding the clock. Is this how it removes? Thanks in advance for your help.
