Just seen this NJC just cruising the forum
You've got me thinking 4 speed should work with cascade and yet I've never seen one in real life , the cascade is bolted between the flywheel and the main gearbox
You can swap yours for a 4speed I you can find the selector cover. You need the top cover because it has another lever to select low box, when you select reverse it shift this lever into low box automatically.
