Most emphatically no. The interior diameters are different from the
GT6 version.

If it's leaking between the plastic reservoir and the cast
iron body, you've either got a cracked reservoir or failed
o rings or both. The o-rings that seal the reservoir to
the body are square in section, and thus a little odd, but
can be found. I've had good luck sealing this up
with blue RTV in addition to the proper o-rings.
