David,
The Burton catalogue mentions the 2wd and 4wd and from the web I see there is also the Transit version of the MT75 box. The catalogue also adds "an aftermarket 2wd gearbox is also available with removable bellhousing". I would think that Morgan used this box as the other boxes have an integral bellhousing.
From the pictures on the web the gear linkage on the Morgan box is different to the Sierra/Granada boxes.
Just my take on things.
If you find something to improve the gear change please let me know as I am looking for an improvement too.
Cheers
John
