The seals I mention about are u shaped.
When I first saw these I was very impressed, they seem to be an ideal solution for a long-door car with the new widescreen frames, and it would be certainly worth consideration.
It has to be said, however, that the usual Morgan manufacturing tolerances (or rather, the lack thereof) means that not all sidescreens will fit in the frames very neatly.
One one friend's Plus 4 they are so tight they have to be forced in from the outside, whilst on another the widescreen isn't held by them at all and had to be padded out with extra neoprene strips.
