Even since the long door trads came along in 1997, the screen and rake have changed, the side-screens have changed, and you have the studded hood and the easy up hood. If you look at pics of studded hood trads with a hardtop, the fit across the screen frame is "tenuous" at best. My experience of hardtops on other cars was that they leak over the header rail. Some hardtops for easy-up cars have the easy-up header rail incorporated in the hard top so the seal should be better. So the chances of finding a decent fit are remote.
Kev had a hardtop on his P4ss but the fit was terrible around the side screens.
The CX cars should be much more consistent, but the fact that few hardtops were made suggests not.
