This crosses to Alcoa part number 88311 which has an outset of 6.66" which gives you a dual spacing of 13.32". Add to that the thickness of a nylon spacer and you may be very, very close to the 13.5 inches required.

No, it won't. It will only help if you can run the pressures spec'd earlier for the 8.25" wheel after achieving the 13.5" dual spacing required.
