Hi Jeff,

I have an '84 automatic, 2 '84 4 speeds, and an '85 4 speed.  Those
coolant parts are indeed different for automatics as they have hose
connections at the bottom for the automatic transmission oil cooler.

Your best bet is to simply call the regular phone number for Bus Depot,
tell them which one you want and get it right the first time.

IIRC BD uses the same photo for both parts ... which is really confusing.
