Or
I will be doing it tomorrow one way or another, so I thought maybe someone would point me in the right direction. Like step one: remove glove compartment etc, or maybe even you could tell me from your book.

I've replaced heater cores on Fords and GM vehicles and never have used a manual. I think what you want to really know up front before you start is, and God forbid, do you have to remove the whole darn dash to do it. This will dramatically affect the time required and when you may choose to start the work. Sorry I can't answer that one. Usually I just look at it and remove what comes naturally and is obviously in the way. This typically includes heater and A/C ducts, possibly the glove box, and then hopefully there will be an access panel you remove to get to the heater core. Once in there and after the heater hoses are removed and drained there are probably a few clips that hold the heater core into the heater box. The clamps are frequently secured with a few small screws. If your wrenching skills are average, you should be able to replace the heater core in an evening if you don't have to remove the dash. If it requires removing the dash, that could be an all day job.

Removal of the radio and heater controls made it simpler to tell what was going on and after removing two layers of plastic up under the center of dash, the heater core was finally exposed and the trble was the plastic line that goes thru the firewall had a split in it and I just replace it with rubber heater hose all the way to the core. Cost about $3.00 and couple of hours. The things we do for kids..
