Phase 1

You might be seeing play in the spline joint. To check for U-joint play turn the shaft.

Looks like a bug screen.

Thanks for sharing that. What was a B47SS ?

Don't teach him that he needs to use better English so he can scam people better.

There was a toilet paper filter adapter kit you could buy for your vehicle. J.C. Whitney sold them. Some manufactured oil filters used the same principle, called depth type filters. They were said to have superior filtration but supposedly testing showed that they were no better than a pleated filter. Hastings filters were made that way, but I think they went away from that.

They bought the tooling from GM and produced the V6 version of the Buick for the CJ.

63 - or maybe 62 Pontiac is my guess.

Did you read the post before yours?

The diesel aircraft engine evolved into the jet engine.

You can be proud of that. Great work.

Some truck makers tipped the engine to the right side in their cab forward trucks. Mack moved the cab to the left.

Those really make it look good.

Turn the cable at the motor end while it is connected at the tach to see if it turns freely.

Torsional vibrations occur twice every time the driveshaft rotates. These result from excessive angles in the u-joints. They also can be caused by driveshafts that have been reassembled out of phase. A phased driveshaft generally is one in which the yokes are in line. However, it is not uncommon for chassis manufacturers to order driveshafts with special phasing. "Torsional vibrations are one of the biggest installation problems you will encounter," Koedam said. Koedam suggested that shops mark driveline components before disassembling them. Mark them in a way that makes it clear that the driveline is being reassembled the same way the manufacturer built it. One good way to identify specially phased drivelines is to look at the weld seam on the tubing. If the weld seam is straight but the yoke is turned, the driveline probably has been built out of phase. https://www.trailer-bodybuilders.com/distributors-upfitters/article/21739166/what-every-shop-must-know-about-drivelines

That gives you something to shoot for Paul.

Credit to you. Taking on a project that is all in pieces can be challenging.

In addition to the Kenworth and Peterbilt, two more of the same style - International and Sterling

The flat auto glass can be cut to size at a glass shop. It looks like it is tinted.

That model was only built as a fire truck.

That wheelbase isn't long enough to put any kind of a bed on it. It is too short for the dump box that is on it. Of course it could be lengthened if you want to do that.

There were not a lot of them with sleepers.

Or an LH. The hard nose is seen on the LJ-X models. I don't know if that was standard on them. I also do not know if there were LHX or LFX models
