Hori real arcade pro EX dual mod

I was thinking about getting the HRAP EX (tekken or regular) now that my ex 2’s downback on one side is slightly faulty. I am going to start entering tournaments soon and would like to dual mod the HRAP EX. I could not find any tuts on google and i searched the forums but could not find anything. Should I just buy a TE instead or is there a way to dual mod it.
BTW here is a pic of the stick: http://www.shopncsx.com/rapextekken6.aspx

Using the stock HORI PCB, no.
It is not Common Ground.

Would have to replace with a Common Ground Xbox 360 Controller.
Then you can Dual Mod with that.

thanks to you both, the guide looks kinda long but ill get to it by tonight
