The Moss catalog lists two different part numbers for the stock cast-iron m=
anifold=E2=80=94depending on the years fitted=E2=80=94but the drawings look=
 identical.  Can anyone supply the casting numbers for each?  We don=E2=80=
=99t know what we have.

Thanks in advance,

The casting number is commonly one digit=20
different from the final part number.  I think=20
they made the finished part drawing first, then=20
made a copy of it to modify the drawing to show=20
more material on the casting before=20
machining.  When assigning drawing numbers, the=20
finished part number was first followed by the=20
casting number.  Some castings can be machined=20
differently to make different finished parts (with different part numbers).
