3) F series Sterling Pre RSC you say 2011 and before would require welding perches to correct width (not an issue).
4)Did Sterling have 4.30 ratio & did they have single anti lock brake set up or was it dual outer hub type?.

1) The ‘99-‘01 E350 extended wagons came with a Dana 70 housing so when you swap to 4.30 gears, you can swap the carrier too and upgrade to 10.5” gears. The cargo vans and regular length wagons mostly got the Dana 60.
2) RSC = roll stability control. The issue is these axles don’t have the center ABS ring which your van needs for ABS and brake proportioning.
3) the F-series has a narrower framer hence needing to move spring perches outboard. Also F-series uses staggered shocks (you could change the van to staggered upper mounts instead)
4) Yes, 4.30 was an available ratio. As long as you get a pre-RSC axle the abs will be compatible. Ford went RSC in the pickups long after the vans. And F250 only initially then F350. I don’t think duallies got it until 2014.
