I was there today from 12 until 4 and missed you guys along with Matt's truck. Really wanted to see that beauty. The show area has gotten a lot larger in the past few years which means a lot more walking.

I had a Garrison hydraulic assist power steering that worked fine but had serious leaks. I sent it out and had all new seals, o-rings and so forth put it. I also had new seals put in the hydraulic cylinder. When reinstalled there was serious wondering. The shop went back over the valve, no luck, same problem. They substituted a rebuilt one, same problem. I ended up taking the Garrison unit off to go back to manual steering. The drag link I found fits 1 1/2" balls and wouldn't you know my knuckle is 1 1/2" and the pitman arm is 1 3/4". The front axle is a FA 505 and the sector shaft at the steering box is 1.125. I came on this old post and wonder, Larry do you still the parts pictured? and if so what's diameter of the ball on the pitman arm?

How about "Big Bucks"

I bet that would do good on Bring a Trailer.

I noticed when I replaced the valve cover gaskets they seemed to bottom out on the mounts as mentioned not making a solid fit to the gasket. I did a bead of RTV to try and compensate. No leaks so far. Here is a picture of the shouldered bolt with a grove around it. I'm not sure what that was for.

There should be a major electrical connection either at the starter or solenoid. It should go from there through the ammeter to the voltage regulator or maybe ignition system depending on how Mack did it. Hopefully you can find a wiring diagram for your model that shows the specifics.

I thought the same thing especially with that apparatus on the rear.

That looks like the same truck I remember as a kid coming to Alexandria, VA with the circus. It was cool to watch it in action.

Here's a picture.

...and they're all red.

Looks like it bid to $10300 and was a no sale. Now asking $21000.

Here's a link to the site. Lots of interesting info including a chart showing values over the past few years. Custom Hauler: Stretched 1965 Mack B53 Tractor - Hemmings.com
