Hi Ken,
Welcome to Morgan ownership.
If it still has a Morgan Moss box, these are different to the Jaguar variety and at least one of the Jag variants has no compatible parts. One of the others is much closer, but still not an identical box...
It may also be worth you hunting down a few of the Morgan books (there are loads of them). One entitled "Moggie", long out of print but does appear on the used market, will help with the Moss box compatibility.
Also, Dennis Glavis, of Morgans West (out on the West Coast), is a mine of information on these cars.
Oh, BTW, welcome to the forum!
