Datsun blue air cleaner color sample

I’d like to repaint my new air cleaner in the original Datsun blue. I’ve looked around, and while Datsun blue/green engine block paint is available, I couldn’t locate a vendor that sells the baby blue air cleaner color on these early trucks. So my plan is to harvest a sample of the color from the inside of my old air cleaner, which has already been mutilated, and attempt to get some new paint to match the color.

Today I spent some time cutting out a section from the inside of my old air cleaner to try to get a flattish coupon of metal with good original color. Easier said than done.

Here’s a shot of the inside of the air cleaner where the paint is in the best condition.

The first thing I did was use some Simple Green and a mild abrasive pad to clean up a couple of the raised areas where it looks like I could get a relatively flat sample.

I was pleased at how much fresher the color looked after cleaning off nearly 50 years of air filter grime.

I used my 4 1/2″ angle grinder with a cut-off wheel to start surgery.

After making a few plunge cuts I got a good-sized sample cut out of the air cleaner.

I removed the adjusting rod that tightens the bottom of the air cleaner to the top of the carburetor. The rod threads into a coupling on the bottom of the air cleaner and the nut holds it from overtightening had to be un-threaded.

And here’s a shot of the coupling that mounts on the carburetor. There is a thin rubber gasket that provides some cushioning in the coupling.
