Finally got the heater core out, practically everything like the hvac controls, few hidden c clips, screws, brackets, bottom heat vents had to move so the heater box can drop to get access. Struggled 3 days trying to get the new heater core to fit. Couldn't get the damn thing installed, ended up ordering different name brand and it fit perfectly. Only thing left to do is put the dash back in now.

In the future for those who needs to change there heater core don't use this piece of S*** APDI/PRO 9010420. The pipe bends are little off, it wont sit properly in the heater box and hits the firewall. Get SPECTRA PREMIUM 94807, it fits perfectly without any issues.
Also Flexible Wire Long Reach Hose Clamp Pliers works really nice getting those 2 heater hose clamps off in tight spaces.

Thanks
