You could modify a Ford Sierra diff. The Buckland has a chain drive from the diff to the rear wheel. Or use the bevel drive from a shaft drive motor bike. There was a great Steampunk trike in either '100% Bike' or its sister 'Trike' a while back. That had a Virago V twin in line, like in the bike and shaft drive to the rear wheel. That setup in a BRA would look great.
