+25 offset plus a 5 spacer is +30. Which seems best to center tires within stock bodywork. Ute I think is 1305 mm drum-to-drum same as coupe.
Is this your mighty ute? The wheels & tyres fill out the guards perfectly.

I ... still maintain that you misunderstood what McDat was saying. The width of the diff he intends to use is entirely related to what backspace the wheels will need to not foul.
My question was about his statement "The diff is set up for 3 3/8 back space". Yes, I wasn't sure what he was saying, but wanted him to clarify. I didn't make any untrue statment did I? I was interested in more specific details, and didn't mean to confuse anyone.
