there isn't any 'cast iron' on these jacks. it's called nodular steel. very tough.
You are correct sir...I had a brain fart. Despite them being nodular, drilling through them wouldn't leave much meat left on the lifting claw.
Red has the simplest/cheapest idea so far...coupla sliding tubes with pads welded on and a few pins = very little to go wrong in the field.
