The spring only came starting in '70 or '71. Before that, there was a plastic 
"sponge" that was supposed to coalese the oil mist and drip it back into the 
crankcase, but those often filled with frost in cold weather and got tossed 
out. I have one of those on the shelf, but haven't seen one on a car since the 
early '70s, when someone at the dealership threw mine away.

I have SST springs which I've made to keep that washer from rattling 
around. I probably have some NOS and used ones, too.

Sounds like a good theory.
