Hi,
I have fitted door checks to two Morgans in the past.
Just make sure when you drill the longer holes in the door you put tape on the drill bit so you don't come through door skin!
Also the chrome dome nuts do come loose so a little bit of Glue stuff to stop that.It is a little tight getting your hands in when fixing it to the car side.
Also keep the leather sraps in case you change your Morgan
