In the USA, we offer a Balmar alternator as an option. This is the Balmar 60-120-SR-IG-SD and it fits perfectly.
Balmar make this for Beta Marine with a side terminal to provide clearance between the alternator and heat exchanger tank. I have attached our fitting instructions.
You will need a curved adjusting arm to make this work properley.
