    Is this what you are looking for?
    http://nastyz28.com/threads/inside-heater-box-cable-bracket-needed.321784/#post-3669496

    Google really helps for these searches.

    try copying and pasting this search in google:

    heater box site:nastyz28.com

    Then look at the images to find what you want.

    Most questions have been answered somewhere here in the past.

    I don't mind answering questions, but you could get the answer almost instantly with a search like this.

    ...Yeah, what Dave Said. I cannot remember if it was Gary S or COPO that turned me on to the Google site search, but it's a really good tool.

    I really find the Google search method much better than the built-in one here. The "Images" tab helps to find what you are looking for.

    It works well on other sites also. I use it on Yenko.net alot.

    If you want to exclude certain words from the search you can add a minus sign ion front of the word to exclude.

    The downside is it will give you lots of posts that will allow you to go off on tangents and spend hours and days and then you'll forget what you were actually looking for.

I was just trying to figure out what is the correct hardware to use to reattach the heater box on those studs that go through the firewall and Which cable goes where.

    One cable is longer than the other which means it needs to go over to the far side of the box but is that the temperature control? The little square door is for heater or defrost? Therefore the shorter cable? Also what bolts to this box right in front of that door? I’ve got four holes where as some heater boxes that I’ve seen do not have those four holes.

    As to the issue of the spring I see what appears to be evidence that there was that bracket bolted on the left side. Is the consensus that the bracket and spring came on all cars?

    When the dumb dumb sealer leaked water at the kick panel vents, I used white house calking that’s used with a calk gun.

    The spring is a very good question that I am still researching.

    Mine did not have a spring when I took it apart, but there was evidence that one may have been there at one time. Many others show no evidence of ever having a spring and there isn't any callout in the AIM for one. I have seen some restoration photos that show it there.

    For the cables, here is a pretty good photo:

    for the nut, the AIM shows part number 9819845 and AMK shows it like this:

    There is also a "special washer" (actually mastic) 3868762 between the outside housing cover and the firewall on these studs.

    It also looks like someone drilled 4 holes around the defroster duct opening. I haven't seen any like that before. The duct is usually only held in place by the bottom tab with one screw.

    Tremendous help thank u so much. I believe I ordered those special washers already and will order those nuts from AMK.

    I notice from the AIM a clip of some type that goes over the arm(s) that the cables attach too. There are no threads so must be held on by pressure? A retention clip of some type?

    What does that lower duct look like that attaches over the defroster duct opening?

    So if that door - defroster duct - transfers from heat to defroster- then it is the shorter cable, correct?

    I also need the bolts for the cables hold downs and other attaching hardware. Original were likely short (1/2?) coarse thread (10-24) cap screw? Anyone know sizes or have loose hardware to reference?

    Ok so now I’m chompin’ at the bit waiting for my heater core so I can put this back together. Everything is cleaned and ready to go. 9DB1CA48-76F7-499C-877D-50F7032F0100.jpeg 90290B41-D432-4A2D-BAFB-947B35B8195A.jpeg 38105397-2C02-4299-B259-6C54D2CF95C5.jpeg 68D2B927-7E06-41DF-9E77-40ABCD934134.jpeg Weeks learning what parts comprise a heater system and securing quality used parts. Who woudda’ Thought. Looking forward to driving the car again.
