Here's an option you might want to explore.....
The body shape of the EM cars is almost exactly the same as the FFR's. In fact, an EM soft-top is the only other manufacturer's top that will fit an FFR without modification.
There are currently two FFR hardtop manufacturers. I would bet with very little work, you could make either one fit the EM pretty easily. Of course, a test fit might be in order before stroking the check!
