Unity rotation to 3DS Max rotation

Hi, here's my problem:

I have some FBXs imported in unity and placed in a level. I want to duplicate the transforms of the FBXs and import it into 3DS Max. Basically, they should appear exactly how they appear in Unity. I have created the connection between unity and Max, but all i need to know is how to transfer the values.

Given that Unity is Y Up and 3DS Max is Z Up, I have the position working fine:

Max_Translation_X = Unity_Translation_Z
Max_Translation_Y = - Unity_Translation_X
Max_Translation_Z = Unity_Translation_Y

Scale transfers directly since the assets have only uniform scale.

The big trouble is with rotation. First I tried transferring over euler angles like the translation values, but that didn't work since I'm not sure about the rotation in values in unity.

Now I'm trying to transfer over the angle axis values into max and use an angle axis rotation inside max, but its still giving me trouble.. does anybody have any clues on how to solve this issue?
