The really early type 3s don't use type 1 coolers.  They are a similar
design, but a bit different.

Ahh, interesting.  I didn't know that VW ditched that deflector plate in
the later years.

Here's the next twist in the story: for engines that use the "normal"
type 3 oil cooler, there are early and late deflector plates.  In
mid-1966 the case changed, and a new deflector plate was introduced to
accommodate the new case's shape.  The later deflector can be used on
early cases, but an early deflector only fits early cases.  If you're
big on originality, early deflector plates are, sadly, quite scarce.  It
took me a few years to find one to go with my 1965 case.
