Tom,
I noted your joining the gang here to learn in anticipation of getting a
van. If the AFM is of such significance to you, why not begin from the
outset with the idea of getting a van with a dead engine and do a
conversion to a Suburu 2.2L or better at the very outset. You would
really have something then. I would never disparage the earlier vans,
but they are from a different era - and they do not perform or ride
anything like a Vanagon. I think the early vans are very cool,
especially the splitties, but man - they don't ride or perform anything
like a Vanagon, and for that difference, I would never harken back to
The Good Old Days for the earlier machines.
