Huge, Gargantuan and Collossal Monk Damage Question

[Grant_Stoom]

I'm trying to figure out the progression for monk damage in much larger forms. My wizard has a newly acquired Monk's Belt which gives him the ability to do unarmed strikes as a 5th level monk damage wise. He also has access to shapechange

So the base Medium 5th level monk unarmed damage is 1d8. Size large for 5th is 2d6. What would the progession be for Huge, Garg or even Collossal sized 5th level monks?

2d8, 3d6, 3d8?

Pretty sure it's
2D8 - huge
4D6 - gargantuan
4D8 - collossal.
