All about heaters.

60-63 (lh side of pic), and 64-66 deluxe heater boxes:
notice in the rear shot, (60-63 is the lower one in the pic) the difference in the rh bolt location, also notice the mount for the "heat" cable is in a different spot.
3rd pic: I noticed that the "heat" cable comes through the back of the 63 box, and through the front of the 60 box, there is also a lower cable guide on the fan box of the 60.
60-63 the "heat" cable mounts inside the box.

just gettin around to the heater part on my 1960 Apache "revitilization". Ordered a cable kit from LMC and was scratchin my head on the heater valve cable not bein long enough. I made one off a lawn mover but it was too hard to move and likely woulda snapped off the heater control arm. I looked inside the core body and its set up with 2 cable clamps, front and back. So I drilled a hole in the firewall and another in the backside of the heater body, same as in the pic above, and the LMC cable is now long enough.
Guess thats why Chevy changed it up.

Since we're talking about heaters....
How do you remove the (deluxe) heater control assy? I've looked all over here & post #49 was helpful but after removing the 2 screws in front and the support screw it will not come out.

Anyone know what size fasteners hold the box to the firewall?

Maybe I can help. I just reinstalled my '64 GMC Deluxe heater and there are two studs that protrude into the cab from under the hood. These studs use a 7/16" nut on the inside of the firewall. There are also six coarse thread bolts that attach the top portion of the heater box to the cowl. These bolts are bolted right into the cowl and use no attaching nuts. However, a couple of the holes in my cowl had been stripped so I used 1/2" speed nuts (available from Home Depot, Lowe's, etc) see image to allow the attaching bolts to be tightened properly.

Has anyone found a source for a heater core for the '60-'63 deluxe (fresh air) heater, either with or without provisions for the Ranco valve?
