Vacuum

I know this has been asked and answered too many times, but
can someone please tell me where to connect the distributor vacuum line to!
74 318, dodge
I have a vacuum line diagram, but for some reason the distributor line is not shown

Thanks
In general, ported (aka timed), but sometimes with various emissions setups the distributor hooks to device that in turn connects to vacuum sources.
Post of the diagram you have.
Also more info. makes this easier.
Is it a California car? manual or automatic? Is it all original? Dart or something else?
Photos of the engine bay can't hurt either.

Lean burn is much later.
