Ok tell me how you have two parity drives with using only three drives.  
It can  not be done.

I was very clear what I wanted to do.

 From my first post:

I think it is out of date as it is using fixit.

I am looking for something that I can use that drops to manually 
partitioning during the install.

The links supplied (two)
     1.     was a link to the handbook using auto partitioning, doesn't
