1976 Chrysler Nissan MN6-33 (SD-33) Wet Exhaust Manifold

[rbest11]

Good Afternoon,

I have a 1976 Chrysler Nissan MN6-33 (SD-33 marine version) in a Maple Leaf 42, located in Vancouver Canada. My Wet exhaust Manifold is looking like it may fail soon. I would apprecicate any advise on where I could find any used ones to purchase. I am on all of the Sd-33 truck sites, but thought I would try here in case someone has one from a repower or any leads. Thank you in advance!
