Quadrajet metering rods?

I bent (and later broke) the metering rods in my quadrajet. it's a post 1975 model with 0.073 jets and 49k rods, which I can't find anywhere. What can I replace them with. It's on a 74 olds engine if that helps.

p.s. please don't say get a new carb, if that was an option I wouldn't be bothering with this.
