1972 heater/ac box screws and nuts

Hi! I'm interested in a clean used set of the hardware that attaches the evaporator / heater box to the firewall. I think it should be 6 screws with the washer that's attached to the head and 3 nuts to attach onto the studs. I've seen the non-ac kits online but can't find ac kits.
Thanks

I am unfamiliar with the 6 screws you mentioned. I recently replaced the heater core on my car and there are 4 or 5 studs with speed nuts holding the box to the firewall.

Mine has only 4 nuts as eons ago I left the one behind the fender well off just in case I ever had to remove the box again, and I am extremely glad I left it off. Made the process so much easier/quicker.

I believe that he is referring to the screws that hold that two halves of the evaporator case together.

Hmm, that would make more sense, but if so he didn't say that:
