What is the best way to do this? Should I use a self tapping fitting or tap to a specific size? Any size recommendations? I'm thinking smaller would be better. I'm assuming the size would be driven by the type/size of bit I'm using to drill through the cast iron upright. Any thoughts?

I would not use a self tapping zerk fitting for the cast iron - it's a total PITA to tap so you need something hard.
I'd probably be looking for the smallest fitting possible to reduce the material removal of the upright.'18 Chevrolet Volt - Electric fun hatch for DD duty!

I used the self-tapping fittings on mine, no problems. The only bitch is that there is nowhere on the mount for the toe arm on the upright to install a fitting, you have to grind a flat spot for the fitting to be installed. The grease likes to go between the arm/upright and the bushing rather than the sleeve and the bushing sometimes though so it is a bit messy to grease them up. My suspension felt much better with the fresh grease and the zerk fittings though. I think it is definitely worth it.function > form
