Replacing heater core

[GMcanblowmyFORD]

well ive got my dash pulled as far back as i can and i took every bolt out that i could see and still cant get the heatercore housing to come back enough to open the lid to replace it, got the one under the hood... ive looked at several wright up now, the one on here looks like the guy cut a hole in his housing to get to his. haynes manual is no help

There are 2 bolts on firewall under the hood. I think 2 on top of heater core. And 1 on the lower left side kind of hidden in the carpet..

There are the two bolts on the firewall that hold the AC dryer on the firewall. These also hold the heater box in place. Also there is one bolt on the bottoom of the heater unit near the transmission tunnel. There are also a few bolts that hold the box to the firewall on the inside along the bottom of the windshield. After removing these bolts you can slide the whole heater box assembly towards you to reveal the four bolts that hold the cover on the heater core box. I had to disconnect my AC lines at the dryer because it would not slide out (into car) with them still hooked up.
