My Volvo unit bolts right up to the adapter on the back of the Sunbeam overdrive transmission. The Volvo unit and Sunbeam unit are nearly identical back to the annulus and the output shaft. The Volvo unit is flanged and the Sunbeam has a male output shaft. The Volvo unit also has a 25% reduction instead of the 22% I think the Sunbeam has. It is a very straight forward interchange.
