Thanks for the replies, guys.
I'm pretty certain that the engine was swapped or they thought they had an '83 at the junkyard when it's an '84. From the photo below, you can see the date stamp on the head showing '84.
Also, I took a photo of the pump part number.
There is a hose going over to the intake manifold where the boost aneroid should be hooked up, but obviously, it's not.
George, I didn't see any stamping that says D24T. Could it be behind the bracket?
