Zacuto universal donut for redrock mattebox?

[scenedirector]

I don't know if this is even the right place to post, but can anyone tell me if I can use the Zacuto universal donut on the Redrock Mattebox?
I hate the donuts they provide and want a universal set up.

Can the Zacuto fit in the back of the mattebox shell? Or are there modifications that I have to make?

Yeah, I can't stand the Red Rock donuts either.

I use the Zacuto universal donut with the Red Rock microMatte Box, but I do it by also using a Chrosziel 100mm step down ring, for a 411 matte box, that has the donut attached to it. I take the Chrosziel ring and insert it into the largest Red Rock donut.

It works well, but it's another $100 for the Chrosziel piece.

Could I use the widest Redrock donut and "glue" the zacuto to it?

Hey Brian! You have a kick ass mattebox, now make a universal donut for it!
