I finally took the time to extract part #000001 from the '87 today. I swear Chevy put this thing on a jig and then built the rest of the car around it. Ugh. Now to put the aluminum replacement in which as you can see doesn't have quite the same pipe bends as the original.
Even though I have the dash pad and bread box out it wasn't really necessary. In the end the only screw I took out from the top ended up being unnecessary.

Reason: Adding image.

my spectra didnt have the right bends. i wasnt smart enough to look before though.
I basically did. In the end pulling the dash pad and bread box were entirely unnecessary. I can see why it may be necessary for 90-96, but these earlier cars there's really nothing to gain as all the screws can be reached from underneath with sockets, extensions, and a universal joint. The only thing I did extra was pull my radio to get at one 7MM screw holding in a long hard plastic duct so it would get out from the front of the heater core box. My interior is also out of the car for a number of other things such as carpet & sound deadening, seat leather/cushion replacement, ZF6 swap, and probably some stereo work while I have easy access to everything.

Scorp508, I assume it was necessary to remove the passenger seat??
It would be a lot more challenging with it in unless you frequently star in a Cirque de Solei show. The seats are held in place by four bolts and two wire connectors which makes pulling them out rather easy.
Same issue when I replaced mine in my 89. I never have creatively cussed as much in my life as I did that day changing the heater core . I agree with Vader, if it goes out in the future, the lines are just getting re-routed and i'll wear an extra layer in the winter
Dear heater core, I hate you.
