Freight Train put a 675 in his B model, maybe he can tell you where to find the thread--he put lots of important details in his posts.

I like how the ad says "The truck has been well-maintained and is in excellent shape, ready to hit the road". The front tires are sunk in the ground, hole in the windshield, and no batteries. It also says gas engine; the hood says diesel. I'd want to hear it run before I paid $8k for it. https://www.ebay.com/itm/375136825027?hash=item5757e5aec3:g:swcAAOSw2fJlhOat&amdata=enc%3AAQAIAAAA4DpY%2F1U6d7slHlNNW6e%2FFlwbAmLnIfcMlBZTS%2FSSA%2B5lldU2g1%2FNIoCs6Tb6NsNZet04%2FCSEkFJNc1RB3SePTS%2B6GzUUDyuuuPfmeX6tVfectkvL%2F4pU3%2Bo8URhtWH28B1uA9oo9x%2BQ%2FhkFglPqn6ioFyVLaP78xnELrgqbHYbAXxeMAEORcimdY%2FoX3BXb9rM%2Bz9siR2rYtoBkUgnTR1xHCOuLh%2FvUrn9jdDhXUquKZ0F8V9wmeCDAo1xjlHfyZmnnWhdv8EUF6IEopWX4V%2B2jg0dpQBrCj9w2PnpApchwQ|tkp%3ABk9SR6bf_oSTYw

You can contact the Mack Historical Museum and ask. https://www.macktruckshistoricalmuseum.org/about/historical-research/

If Paul Harvey saw the state of our country today, he'd be disgusted.

Is the 6NZ a 3406 or a C-15? I left Cat in 1999, they hadn't come out with C-15s yet.

That's a fine looking Pete parked behind the MH!

It probably came without steer brakes, I've seen trucks as new as 1975 without factory installed brakes.

They were used on ashtrays, among other things.

On the older Macks, the manual steer trucks usually had 22" wheels and the power steer trucks had 20".

I don't know if this has been brought up before, but Mack has a website with some pretty nice shirts, hats, die cast, etc. https://mackshop.com/retailstore/

I've talked to guys at the truck shows who had a custom headliner made at an upholstery shop. Prolly lots of green pieces of paper.

Great work! If that truck had a million miles on it, you can imagine the vibration that needle experienced. I've seen a lot of them broken off.

I've never seen brakes hooked up without QR valves, I don't know what negatives there would be. I achieved anti-compounding by using a QR-1C valve (not very expensive, very easy to plumb).

It's a real shame, those trucks were probably scrapped. I imagine they led hard lives.

On the later trucks, it's called the tractor protection valve (Bendix TP-3). Maybe the older trucks it's just called a relay valve?

It must have been right around 1968, you can find several photos of that nose style on the web. When you look for 1967 Brockways, you don't see many (possibly these were built in '67 but maybe titled as '68 models).

I have seen several questions about the beige interior paint over the years, but haven't seen anyone come up with a code number for it.

If you hover your pointer over the web address of the auction in the top bar, right click and click on "copy". Then when you type your message on here, just right click and click on "paste".

On the 673 motor it has a dowel so you can pull the pump without retiming. I don't know about the later engines.

I don't know how the price of a Brockway compared with other trucks, I figured since they were hand-built they would cost more. The poem calls them cheap. Pretty good poem!

Elevator bolts. We used them when we built roll-up trailer doors, they pull down almost flush with the surface (except Apitong is pretty hard, sounds like Matt is going the correct route).

Since I got the Mack "done", I started tinkering around with the Brock. Check out this video, and then watch the "will it start" video after it.

Really interesting article about the Powerliner. At the end they mention an experimental Hall-Scott 2181 c.i. gas engine--probably had to pull a gas tanker to keep it fed! https://www.curbsideclassic.com/blog/trucks-and-heavy-equipment/truck-history-1973-freightliner-powerliner-its-giant-1150-cubic-inch-19l-600-hp-cummins-kta-600-was-the-largest-diesel-in-production-highway-trucks/
