How do I get to my heater core?

[discot315]

I just got my new motor in and completly back together and started it and had it running but the heater core decided to go like the 3rd time I started it. So I got the new heater core because the old one actually broke where the hose attaches, But I dont know how to get to the heater core. I took the cover off that covers the blower motor and I can see the heater core but cant get at it, Im thinking I have to from the inside. I took the glove box off and was looking and theres just like a big black plastic piece covering everything. Do I have to take all that out to get at it? Any tips would help out alot. Thanks
