alignment question on Romer

I am trying to align a part on our Romer and the print is not the greatest in geometric callouts. Please review attached print.
I have 3 cylinders as Datums. I have not aligned a part using all cylinders and would appreciate help. Print is difficult.

I have the A datum facing up in the Z axis on the table.

I am thinking I need to create an origin for X and Y at the intersection of A and C. and call that a different datum. I am thinking the alignment would be.

Level: A +/-X,Y, or Z Zplus

Rotate: C +/-X,Y, or Z X plus

Origins:
X: c

Y: c

Z: A

Thank you for advice.

Colin,

I almost had it.... Below is my understanding of your suggested alignment. Just had a question on the rotation to X plus. Please confirm if X plus is the right direction. After studying print, I am thinking the direction could be X minus instead. What do you think?
So I do not need to make a point for the origin. The system will know that is the origin point, right?

Level: cyl A to Z plus

Rotate: cyl C to X plus??

Origins:
X: A
Y: A
Z: C
