I just went through the joy of trying to figure out what my spline was.
Part of my story you'll find here...

As a 72, I would almost be certain (well, at least as certain as I can be without a photo and some measurements) that yours is an earlier spline.
When finding a boss they should have a list of vehicles and the appropriate model number, yours should fit in Beetle 19?? to 1973/4.
As to where you would get a boss, you would be best to start with a place that sells steering wheels.
The PCD of your bolts will be critical, as will making sure you can hook up your horn.
Trying your local supercheap or repco will bring no luck, because the boss is highly unlikely to be a stock item, but they can probably order it in for you.
That may be a safer way of going about it than with a internet seller... but here's one to look at anyway.
