Bill,
Thanks for the followup.  I suspected that this was the answer.  I don't
think that I will be able to use the stock oil cooler in the RV-4, but I
will continue to take a look at this; a 90 degree adapter is probably
possible but would alsmost certainly be to wide.   Mike Wills came to
this same conclusion but I hoped that I was wrong about the flow rates
on a banjo fitting.

BTW I have heard a few bad things about Earl's oil coolers from
friends of mine in auto racing. These are rumors of course.
