1972 Models had a drum front brake and the speedometer drive was from the transmission.
1973 models were the first model to have a disc brake on the front. They also were the first model to have the speedometer drive off the front wheel. The front hub with a disc brake allowed enough room to use a speedo drive.
Now, a 1973 may have still have a speedometer drive hole in the trans case, I am not sure of this though. It would of course been plugged.

The tach drive should come off the top of the timing cover.
The transmission speedo drive comes the front of the transmission.
Here is a really crappy pic of the locations.....

Edit Note: O-oops, sorry....... I misread your post. You were only saying your 1973 only has a tach drive.

NOT TRUE AT ALL!
You need a battery to:
Power the ignition.
Power the lights.
Power the horn.
If you had a 1970 or earlier XLCH with a magneto ignition and did not want to use lights, horn etc....... Then with a kick starter on such a machine, you will not need a battery.
Otherwise, you need a battery.

I thought that sounded odd. I'm also hearing conflicting reports on how hard it is to convert a rear drum brake to disc. Isn't it illegal not to use lights?

You need a different hub.
A different set up for the brake pedal, along with a master cylinder, calipers etc.
Then you have to put it all together and fit it to your bike. I would never do it myself. Too involved for what you get out of it.
And yes, riding without lights will get you a ticket and also perhaps sudden death if a car pulls out in front of you.
In any state that requires an inspection sticker..... you will not be able to get a sticker if you have no lights.
