My alma mater.

I don't see anybody I know...

Good eye.

You may already know but that is to control rear axle whine (as a result of "non conjugal meshing action" of the ring an pinion). The resulting disturbance is transmitted up the driveshaft, causing it to wind up and relax like a rubber band, the order of the disturbance being commensurate with the number of teeth on the pinion gear. The damper is tuned to attack the resonant frequency of the shaft. You can put them on the rear axle companion flange as well, but they are not as effective because the amplitude of the disturbance is bigger the farther forward you go.

We used a lot of those on the old Astro/Safari vans, and on GMT400 pickups with the aluminum one piece shafts.

I've never seen anything like that before. I suspect they guide the hood into place, but also hold it open in position while driving the attaching bolts. That way you can release the hoist and let it go back to pick up the next job.

how about the guy under the orange one with a cigarette hanging out out his mouth?

I just found this b&w shot in my files. Those shelving units must have been enormously strong to hold 6 complete engines at one time, but imagine the load that must be on those bottom units that are supporting 6 engines, stacked 5 high?

I had a feeling that was its intended purpose but was never 100%. Thanks for for the explanation.

More Flint Production.

That guy looks like he just walked in off the street.
Short sleeve shirt,no safety glasses,loose fitting casual pants,soft toed shoes and is he even wearing socks?

I think OSHA was a toothless tiger back then ...

He’s an engineer...
