Fseries was 8x165 until 97, then they changed to 8x170 98 and up. Not sure eseries ever went to 8x170 other than 4wd converted vans like boywonder stated. Either way adapters will get ya whatever wheels you want.
There were older Alcoa wheels available in the 8x165 pattern that came on the vans (and trucks) stock. Used to see them for sale a lot on cl, but it’s been a while since I’ve seen any.
