^^^ trucks and vans had the same bolt pattern through 1999 I believe. So depending on what year his rigs are, they could interchange.
His quigley could have stock f350 hubs as well depending on year. Meaning the fronts could be 8x170 and the rear could have 8x165 to 8x170 adapters on the original oem axle, meaning if both rigs are later years they could also interchange.
