Malcolm,
Places that can leak mysteriously include:
Heater air box
Seams at fender to cowling
Inner fender tops
Windshield wiper bases
Front snap of the fabric top
and more
I would start with the fender seams. That T-shaped filler piece
between fender and cowling should be water tight on top, and also the
fender should be sealed at its forward end, just under the back edge of
the bonnet where there is a vertical gap of about an inch.
If the top leaks at that front corner a tiny line of water runs down
the windscreen column and drips on the floor. You don't see the water
running on the aluminum but can feel it. More indicative than feeling it
is to use a kleenex, as it will show drops of water that fingers may not
feel. A palliative for this leak is to park the car in a different
position on a slope.
Best of luck. Leaks can be difficult to locate.
