72 heater core w/ac replacement

Hi guys . I knew this day was coming.  It was probably discussed before.  I did a search but couldn't find an exact how to. Does anybody have any tricks to doing this enjoyable job? And while I'm there I might as well change the evap coil. -Rick- 

to make the job easy, remove the outer & inner fender, pull the engine and dash

if you're going to change the blower motor, heater core and evap core you might as well go with an aftermarket unit?

Just looked at the manual.  Makes more scents when you see pics.  Basically split the air box in the car to access the h.c.  Actually doesn't look that hard. I'll remove the pass seat probably easier that way . Thanks cj and rock

iirc the inside ones are down along the bottom of the box by the tranny hump and the rest outside worst is the one straight up to the cowl, not bad if you know where it is remove the fan box then the rest aren't too bad, you don't need to remove the outer a/c box unless you change the evap core.
 worst part is the peg clips holding the vent tubes to the box inside, they pop out but getting to a couple are a bit of a pain, just remove only the part of the vent system needed to get the box off

Plug your ears my dear, that's the HBO I'm listening to.

Please take pics along the way. I have to do the both of them in my car.
