I understand many of the old classic cars still running in Cuba have been converted to Russian marine Diesel engines over the years. Maybe a similar approach would be easier for you.
I'm actually doing this to my 55 Bedford A5 6 tons truck. A Perkins 6.354. So now I'm surfing the WWW to find a good transmission to put behind it, I've been looking at NP542. They are avalible with a SAE bellhousing for easier conversions. But I think about cutting a plain plate out for that too.
