My Micro-step drive and PLC need a simple resistor network between their i/o ports.The optocouplers in the stepper drive have a max input current of 15mA, while the controller needs to output at least 20mA to give valid signals. The circuit below satisfies these requirements.

What is a good way to mount these resistors in my PLC cabinet?
Are there terminal blocks that accommodate through hole resistors nicely, or would panel/chassis mount resistors be a better solution?
I have looked at some of the terminal blocks out there, but I haven't seen an elegant solution for adding through hole components. I have looked at panel mount resistors as well, but the power ratings are often much greater than I need.
