Are all 360's balanced the same?

318's were only internally balanced, 340's were either internally balanced (forged steel cranks) or externally balanced (cast cranks). All 360 la's are externally balanced from the factory. If you have the Tc from a 360 you just bolt it up. If the Tc is from a 318 you need that adapter. If you have a Tc from a 340...good luck! Check the part number on it and look for weights to be welded on. Only the neutrally balanced 340 would work with the adapter.
