Chris, I don't have that bowden cable but mine broke as well several years ago. It had a plastic sleeve which broke at one end near the fitting. I had reattached it with epoxy which held for a little while but eventually broke again. Jason had a replacement cable at the time and I was pleasantly surprised to see it had a spiral steel sleeve. I doubt that it will break. I'm guessing yours is plastic? My advice is to find one with the spiral steel sleeve if you have a choice.
Below is a pic of my original cable (bottom) and the replacement (top).
There is one for sale in here; The Cadi Shack 63 64 cadillac parts and info | Facebook
I have the metal spiral type for 70.00 plus shipping.
