Just one observation about panhard rods. I've been looking into this recently.
If your Morgan has the old arrangement where the fuel tank rests on the floor boards there's plenty of room for a panhard rod.
But where the fuel tank sits on a steel framed cradle, still on wood, there is significantly less space between the diff cover and the tank. On my Plus 4 its a hand thickness, whereas on my Roadster its more like a hand width.The rod lies below the diff centreline, but with tight clearance there's a potential for knocking.
I'll be fitting a panhard rod to my Roadster over winter, all being well, along with some other stuff.
Not sure about the Plus 4 yet..........
