I think mine are either Simmonds or Heart of England and are tinted grey. The way I fixed the hinges mean that they stay up & over the screen top as wind deflectors and the hood fits over the top. I believe that the Holden ones are not the right width to fit the morgan screen fittings, but worth checking.
Do you have any photos of the way you've fitted them Dave?
I have some that clip over the screen frame but when the hoods on they create quite a gap and the rain poors in.
