Suitable alternator?

[flyerncle]

I am no sparky but all it had was a large live feed (battery feed) and a wire for the battery warning light.The whole unit is about 6x8 inches and has three mounting holes 2 lower and 1 upper when fitted vertically to the rear of the engine at the O/S of the engine.
The adjuster is sprung or you could use some sort of adjustable sliding pulley and bolt to a suitable plate or the chassis, just make sure it is aligned perfectly.
