I do not condone or endorse this kind of reckless behavior….
Send it this way!This is some seriously wet snow we are seeing. Perfect for parking lot donuts!
After that Xmas tree trip, it became very apparent a lot of cold air comes in. Decided to address a couple items. First, I readjusted the cowl vent because I stuck a flashlight pointing down into it, closed the vent and looked under the dash and there was a huge gap. Got it snugged you tight so no mate air coming in there when closed. Also a couple missing grommets that were in place, just pushed out of the holes so got them back in.
Next, I took a look at the blower fan. Mine isn’t stock, was replaced long ago with a similar size unit, but I think the squirrel cage fan is a lot smaller than stock. Opening is nearly 5” and the cage in there is only 4-1/8”. I picked up a new fan from Napa I’d read about: 655-1747. I’m going to return it because it seems to only turn about the same rpm as the one in there. I have no way to measure this, just seems about the same. It’s also way louder. It needs modified to fit and my current fan wheel would also need modified to fit it. Didn’t want to go through all that and end up the same. So I took my existing blower motor apart, cleaned it, soldered new wires in and put it back. Blows about the same.
Is this for your 78? I’m working on a 1970 so the fan and housing are smaller. But what’s the diameter of that fan wheel?I've been working on rebuilding my blower box. I have purchased a Spal 001-A53-03S, which isn't the normal "swap", but it seems like it would provide more air. I'm swapping in a vintage air system but keeping the stock blower box, which is the source of the inspiration. I haven't gotten everything wired in yet, but hooking the blower to 12V works well.
Cage size is a pretty close match with the original blower.
I removed the housing and roughly milled an adapter plate for the stock blower box.

Not finished yet though so no determination on how well it is going to go.
Indeed, '78. I didn't even realize there was a blower box change in years there, but it makes sense. Diameter of the wheel on the Spal is 127mm, height is 86mm.Is this for your 78? I’m working on a 1970 so the fan and housing are smaller. But what’s the diameter of that fan wheel?
Thanks for posting.
Would love to see how you tie this into the vintage air system.I've been working on rebuilding my blower box.

Me too! I have an idea to tie a better fan and an evaporator into a modified stock duct, then run it through the factory heater. May not be the optimal setup for cooling but should make it more bearable and look really factory. But this fan I have isn’t up to that task.Would love to see how you tie this into the vintage air system.
I am using the vintage air heater/evaporator but have removed the blower. Instead, I've re-routed the heating and A/C lines around the stock blower, and plan on building a custom tunnel between the stock blower location and the vintage air unit. It won't look factory, but it will be functional. In the northwest I feel like it is critical to be able to pull fresh air to defrost the windows vs the vintage air setup, which I have never liked the idea of only having only recirculating air. I've got a slightly different engine setup, but this should work irrespective. I'll post pics on my build thread soon (still sorting out some firewall/fitment issues at the moment and trying to get the battery box installed).Me too!

I’d love to see it. I completely agree about the fresh air; sounds like we are thinking of a similar solution. I am not a fan of the current vintage air louvers design for the 40. Looks like an afterthought like it just doesn’t belong there.I am using the vintage air heater/evaporator but have removed the blower.

My resistor was good, just no fan.Glad that blower worked out! Did you find another resistor for it?
I did that same repair on my door limiter last year. Tough to weld that torn metal but I made it work.
Have you found any Capri Blue in a can for touchups? Or do you use a spray gun?
I had time today to work on my radio install. Got a Bluetooth unit from @thecrazygreek and some Kenwood speakers. I wanted a semi hidden look so made some brackets and mounted the speakers under the dash above the kick vent, keeping the vent fully functional and still easy to reach by foot. Sprayed the brackets with rustoleum satin nickel and I’m pretty pleased. They were a pain to install because I was trying to use existing firewall holes for the inner mounts but I like the end result. Speakers don’t sound great but that’s likely because they are cheap, $30 specials and I really don’t know much about car audio. View attachment 3209544
