Hard Top

[lmehr@domain.elided (Louis Mehr)]

Good Morning All,

1/ Last weekend I bought a fairly scruffy hardtop.  It's in primer and the headlining is shot.  
However, the top  makes  a  huge difference when driving the car.   Up to now I relied on my disintegrating soft top only in emergencies - it was so bad that it only went up in the rain. 
At last I can turn around and see out of the rear quarters and no longer are my ears cold - but I can't see the sky above.
It occurred to me that the best of both worlds for the British climate  may be a hard top with a full length sunroof.
Has anyone fitted a sunroof to a hardtop - full length, canvas, electric  or otherwise ?
What scrap vehicle would be a suitable donor for a sunroof - is this viable ?
Are there any articles on this subject in circulation ?

2/  The power steering fluid level seems to need topping up after every couple of journeys - there are no obvious leaks.  Is this normal ?

3/ I think the carbs are running rich.   Is home tuning a bad idea ?  I have a CO meter and flowmeter  which I used on my old Spitfire.  I bought the service your Stag video but the issue of setting up the carbs is dismissed with the statement "take it to a specialist"

4/ How noisy should the overdrive gearbox be ?  There is some whine which is quite annoying.  Is this usual ?
