I wondered if the Ghibli might have similar ducting... Just looking at it, it's clear it's not a homebrew solution. The manifold/splitter fits the evaporator box perfectly and is clearly a production (for who knows what) item. The ducts have some sort of serious staples attaching them to the manifold/splitter.
The blower motor looks a LOT like a Pantera model, except to get the motor/fans out, the shell comes apart in a top half / bottom half manner. From what I've seen on Pantera's the motor & fans detach from the shell at the rear.
It's a 4 wire blower motor (3 speed). The vents on the left and right have no markings on them it all. When I have a chance I will take the evaporator box apart and look for any markings in hopes of finding more info.
The engine goes back in this weekend !!!
