Towbar and rear step bumper brackets

[johnreese1]

Need help with type of brackets needed for 2006 sr Xcab ute. I have used straight brackets from the previous model and welded 2x2 box to the brackets for the spacing. I now want to attach a towbar and still use the step bumper. There are a few different types of brackets for different models, not sure which ones suit my model.
Anyone shed some light on my problem please.
