Cam Driven Vacuum Pump

[Cudapile]

I have a 72 Challenger JH23H parts car.
I found this old and new pump in it.
The directions show it mounting near the distributor. Was this a factory part and how did it mount and what did it do.
Is it worth anything.
Thanks

Nothing Mopar about it.
It looks like you have the installation guide.
That should answer your question.

Thanks for the info, one less thing to figure out.

This typical on diesel engines .
