That engine looks like a factory egr-less manifold for non-turbo!
Some with an early 300D should grab it, easy swap with new $5 gasket.

IF anyone travels back towards middle southeast, from getting Funola's parts in CT, please let me know as I would like to get his rims
I'll put gas $ in for delivery
