Do these attach the blower motor to the heater box (engineside) as the name suggests or the heater/AC box to the firewall? To me they look like the one's that attach the box to the firewall, not the blower. Trying to figure out why there are 6 for an A/C car, as the heater A/C box is attached using 5 studs....

what was original finish on both the nuts that bolt the blower motor to heater box as well as the heater/AC box to firewall? my original nuts that hold the box to the firewall look just like these but have a gray plated finish on them and are not gold CAD-like as these are?

trying to figure if the appearance of the finish on mine is as it looked new or as it looks after 42 years...

also in a case like this do you go with what is on your car if you think it has been there possibly its whole life as opposed to something that is a repop?

Thanks
