I have chased the origins of many leaks that wind up dripping on my leg, as has been suggested the scuttle and ash frame joint is a favourite route.
I have glued a rubber seal (woollies) to the scuttle, under the bonnet. This provides enough ground to seat securely onto the scuttle and privide space to adhere the under bonnet tape for a trad look.
The job looks fairly neat, and so far is preventing the water from the bonnet/ scuttle from ingress.
Other sites of ingress I have found is under the bonnet tool box (1988 4/4) and water that made its way to a plate on the scuttle directly above the steering shaft.
Window wiper gaskets are yet another site of ingress.
Anyway - stopping water from these sites is only part of the problem as water can find many other ways into the cockpit. Hey Ho,
All the best
