Gerard, some of the up-market Dodge vans then came with chromed steel wheels, sort of a 'bent spoke' design, IIRC. That's maybe what you're seeing. I have to wonder if the added length of the 230 puts it close to or over the allowable weight on the rear axle, tho'.
Point of info... the Xplorer company of today has been thru two or three owners (and a couple of resurrections?) since their Dodge van B's were built. Doubt there's any factory support for the old B's.
But (sudden memory) member "Gizmo's Mom" & her hubby had an Xplorer, a 230 I think. I haven't seen her around for a while, but forum searches for the user name or Xplorer might be productive.
