Sorry if I am poking my nose in
The 2 litre Twin Cam Sierra engine is a good strong petrol engine for the Tranny, pulls very well with loads of torque
Saw a carbed twink engined Tranny at the breakers a few months ago, wouldn't imagine that it would be that difficult to get one of those up & running.
Not sure if the Diesel MT75 box is the same as the one in the Sierra though !!
Very nearly bought the engine & box to replace the Pinto engine in mine, sold the Tranny instead
