Hi Ken. Not being an owner yet, i can only give an informed opinion based from what i have seen.
First of all, the Fairbourne GT and the Morgan heritage are the same height. The Morgan one is slightly wider than the Fairbourne one.
Do you drive alone, why not swap out the driver side one for a custom sized one?
The screens are Lexan(makrolon), easy to cut on a band saw.
John.
