Hi Andrew
Depends.....tried it on my 08 car and the sidescreens would not engage without first bending them in a little every time I closed the door, at the same time got a second pair for a friends 07 car (both +4's) and they worked perfectly every time.
Seems around 2011 but knowing Morgan could be a wide introduction time?
They certainly can to cars with the easy up hood, available as stick on units for a little over £20 from memory, best bet is to try the dealer in Perth for advice. They take a few seconds to fit and then trim to size.
