OK, there is a detail I'd like to clear up, it seems
those that know are tossing around the angle of the
motor w/ and without the use of an adapter plate, but
I am con-fu-sed.

15 degree =

51 degree =

You can bolt up an I4 to an air-cooled Vanagon
trans-axle by:

You can make use of a water cooled but non diesel bus
with this project by using (plate optional or
required?):

My basic question break down into three area;

- When is the plate a must have?

- Which way = 15 degrees, which = 51 degrees?

- If I start with a Vanagon that has a water-cooled
motor, wouldn't this reduce the parts needed to
install a water cooled I4?

Thx for the discourse people.
