===Stack unit - removing glass===
To remove the perspex window of the stack unit it should first be removed from the vehicle using the above procedure.

The glass is held in place using a black bath sealant type substance and this should be scraped away as best as possible. I, very gently, used a stanley knife blade to separate the perspex window from the plastic surrounding lip. This is a job that should be done very carefully and slowly otherwise there will be obvious damage to the unit. I did this over a period of days as not to become too frustrated with it. When I started to get frustrated with it I went off and had a beer and tried again the next day....not a job to do if you're in a rush!

Once I was satisfied that I had removed as much of the black sealant as I could I gently started to insert broken stanley blade segments into the gap and really gently try to lever the perspex out of the unit. I started along the bottom edge and in the bottom corners in case I made any marks on the unit as these areas are somewhat hidden by the steering column surround . NOTE: stanley blades are bloody sharp and you could very easily cut yourself. Don't say I didn't warn you!

Once I had managed to lift a corner I continued to separate the black sealant at the back of the perspex. I then added another segment of broken stanley blade to keep it lifted and slowly worked my way round the edge. Be careful not to lever the perspex too much or it might break and i'm not so sure how easy or cheap it would be to get a replacement.

To refit the glass I managed to find some black bath sealant at my local DIY shop. I first cleaned all of the surfaces as best as I could and then pushed the glass back in place. I then sparingly squeezed some of the sealant around the edge of the glass clearing away the excess immediatlely. I decided not to put any sealant behind the glass as the glass already seemed a reasonably tight fit and just in case i had to do the same job next week, It is a Lotus after all! I just put enough around the edge to seal it so that moisture, condensation etc shouldn't be able to get in.

My best advice is to take your time with this job. It's a bit long but i think the slower you do it the less likely you are to damage the unit. Good luck!
