So has anyone removed a heater core recently and remembered if it was a serious PITA? Im looking at my car and thinking that its probably not a great time.
 
If I remember correctly, remove the cardboard glove box, nuts and plate at the fan motor under the hood, remove heater hoses, remove wire connections under dash, remove defrost hoses, and most important remove the long hook in the fresh air box. Arm thru glove box and one under dash it should drop right out.
Above is for non AC cars.
Detroit Muscle Tech has a great resto kit for the heater box.
 
Pretty much as described by pa340dart, but I seem to recall there's one nut closer to the center of the firewall that supports the end of the heater box as well. Don't forget to remove the defroster duct hoses, the clips are a real pita, but they should come off the box outlets pretty easily. Once you get the box out, then you simply remove the spring clips and it splits. I recommend at least trying to get as much coolant out of the core as possible as it will end up on your carpet when you are turning the box to remove it. If you've never done it before it will probably take you about 2 hours or less to remove it. As for the long hook through the right side vent, you simply loosen the 5/16 head bolt on the bottom of the vent area and swing the rod away from the cowl top.
 
In case you get depressed, the Dakotas/ rams you have to pull the seats for room to work, drop the column and pull the entire dash, and THEN you still get to remove the heater, and of course discharge the AC if equipped.

I've had guys claim they do it simpler but they are a lot younger, faster, stronger, and more agile than me!!
