Re: heater core box
The A/C box is quite a bit bigger,if I remember correctly even the heater hose holes in the firewall are in a different spot.

Re: heater core box
They are different. The heater core is mounted inside that box, and as mentioned, the lines go through the fire wall more to the passenger side of the truck on the AC box, than where yours go now.
