Ed, be aware that this 1965 "Falcon" Van is really an Econoline.

Ford stuck Falcon emblems on 1961/67 Econolines, but they ain't Falcons in any way, shape or form.

You won't find any parts listed for any 1961/67 Falcon Van or Falcon Pickup in any passenger cars parts catalog.

200's have 7 mains, 144/170's have 4.
