Redrill the axle flange to HQ/WB stud pattern using a stud with a larger head. I can't find the details of the studs I used, sorry.

You would be better off finding a R31 Skyline diff. Exactly the same diff but you won't need to shorten the housing or have new axles made.
Any engineering shop should be able to fill / drill the axles & rotors to whatever pattern you want.

Or get new billet axles made with the right stud pattern and centre flange diameter.

Thanks guys, I think billet axles and redrilled VN rotors will be the way to go
