I do not think they manufacture CG lock anymore. I had two on my Elise, then moved first one and then the other to my Roadster. Both broke after a while, but were decent add-ons as long as they lasted. Last time I was looking for them I was directed to and bought another plastic/rubber gadget called Shoft, complete junk which I threw away after ten minutes of testing.
Now may I ask, why a roll bar? To actually roll a Morgan is quite an achievement, extremely unlikely to happen. I have never heard of one to this day, and if one is not tracking the car, I cannot see any real advantage exept perhaps cosmetic. Not my choice, but every man to his own. It is quite expensive and unless one mods the tonneau cover (which also will be a few quid) one loses that convenience. It must restrain access to the luggage shelf and adds wheght. And then there is the rear mirror issue that I had not thought of. As I said, every man to his own - but I think it is a good idea to make and sober analysis of pros and cons, what really comes out of it.
