Maybe your other car has aftermarket lines? Here's a photo of the original differential pulled out of my 1972 T/A. It had the factory coil wrapped lines in it.

And as an added bonus, a photo of the same car's leaf spring with the original part number, next to the restored spring.

And if you shop right now, you will get the actual Ronco Spring Stencil - it dices, it slices, it makes your springs look like new!

(Just enlarge the photo to make the ruler actual size and you have correct stencil)

A mind is a terrible thing to waste. You are of course right on the brake line. Here is the 12 bolt I built last year to go in the Red Car when the engine gets swapped. Each day presents a new opportunity to learn.

You still have time to finish it like the "perv or prevailing" method too....

On the right we have the cast iron paint for cast "pumkin" parts, and aluminum paint for steel "tube" parts, etc.

On the left add the black fog to back side for gm look.

Still going through the stack of stuff NJSteve sent with the Black Car. Tonight I found a copy of the 1986 Hemmings ad that our Old Pal Lloyd from Texas found which was advertising the Black Car for sale. It's pretty cool, as is the main thread which centered on Lloyds hunt for a mythical GTO in old Hemmings. Lots of cool ads.

Here's the link to his post on the Black Car and a copy of the ad:

...and here is a link to the main post on Lloyds mythical hunt and a link to a side road the discussion took. It's worth a trip down memory lane. I miss Lloyd. He always had a lot to add that was worthwhile.

I spent most of the day killing time under the hood of the Black Car cleaning stuff up and straightening a few things out. I am planning to swap air cleaners at least temporarily so that I can blast and repaint the one on the car now. I have a nice "new" one I did for the red Car that I will put on it for the time being. However, I am perplexed by the vacuum hose routing. I can find nothing in the service manual or restoration guide. The existing air cleaner was not connected to a vacuum source. The vacuum fitting on the front drivers side of the manifold is capped off and there is nothing connected to the air cleaner. It seems like the vacuum source should connect to one side of the air inlet sensor mounted in the air cleaner and that that other nipple on that sensor should then connect to the two vacuum diaphrams. However, the way the hoses are currently hooked up has both vacuum diaphrams hooked to separate nipples on the air intake sensor (see picture label #1) and then there is a "t" fitting on one of the hoses going to the vacuum diaphrams (see picture label #2). My assumption is that this was intended for a hose to connect to that "t" fitting that was then connected on the other end to the vacuum source. This would mean however that one of the air cleaner intake flappers would always be open and the other would open when the car warmed up. Can anyone provide a diagram or some direction?

I have attached a second picture that shows the replacement vacuum hose set up I bought from PY. It appears to be designed the way I think seems correct - both vacuum actuators hooked to one side of the air inlet sensor, but the separate hose that I think would go to a vacuum source and the other side of the sensor is only about 6" long and won't come close to reaching the intake nipple on the front drivers side.

Lastly, I have a picture of the breather tube that was on the Black Car and the repop piece I bought from PY for the Red Car. I refinished the repop piece with black manganese from Palmetto, while the original is just bare metal. Which is correct? What about the difference in shape?

Yes this is a air cleaner for a 400, but 400 uses 2 vacuum flaps , same as the 455 unit.

Bruce,

Thanks again. I think this is right....

Now what vacuum source is "correct" to connect to the other nipple on the air inlet switch? Is it the fitting in the manifold front, driver's side? That seems like a long run from the rear of the air cleaner. Also, what is the conventional wisdom between yellow stripe vacuum hose vs. white stripe? Did the factory use both?
