Cooling System Redux - Heater Assembly removed

Game on! Removed the battery and battery tray (not shown) and the AC auxillary blower unit (or crotch blower as I call it) so I could get at the heater assembly. You can see the AC blower dangling above the shifter. All this so I could:

A. Swap the factory blower motor for the Chevy Blazer blower motor

B. Replace the aging heater core

Most likely I will remove the entire dash temporarily to put the assembly back in place.
