I have a '64 ss with A/C using the air/heater knobs is pretty tough the "Air" and "Heater/AC" levers being the most difficult and squeeky.

I've oiled the cables but I'm still getting a lot of resistance and rusty sound coming from the "air" lever and what I think? is the blend door in the engine bay.

My question is there an easy way to oil that door? I tried to remove this cover in the engine bay to get to it, it looked like it was only these 4 bolts but undoing them it didn't budge at all. Trying to spray oil down the lever handle (blue arrow) didn't get oil where it needed to be. Thoughts?

Your cables are froze up. Time to replace them.

I had the same problem with my air conditioned 1962, and no matter what I did, the final decision to replace the cables was made after I broke one arm trying to get it to move. I have never seen where a door gets that difficult to move, and oiling it would make the difference. I bought my replacement cables on eBay, since it was less expensive than going directly to the suppliers website. The savings was on the cost of shipping.
The bad news, is that you might have to remove the heater box to replace some of the cables. I have had my heater box out so many times, that I can do it with my eyes closed.

When I oiled the cables I took them off the lever that moves the door in engine bay (blue arrow). Oiled them and when detached they move smooth as butter. Manually flipping the lever (blue arrow) with my hand the door screeches something awful with a fair bit of resistance. Put the cable back on on its almost froze again.

It just seems like if it was the cable thats bad it would hard to move even detached?

how to I get the heater box off?

With great difficulty. You will have to consult your service manual. On my 1962, I have a bunch of nuts that are on studs that have to be removed, and the heater box pulls out from the firewall. You also have to remove the air conditioning ductwork, which is a pain to do. Don't remember if the glove box has to come out, since mine has been out for a while. It isn't difficult, but it is time consuming. Once you have the cable out, you could coil it and try soaking it in EvapoRust, and then lube it with Sea Foam Deep Creep penetrant. Best stuff that I have ever used!
