Tapping the steering arms is a better option, but you may want to go all the way thru and use the stop threads as filler. I would look into repop stops made of rubber, as urethane doesn't really give on contact to soften the force of the steering arm against the tube. If you find a good solution, I may have to "borrow" it...
I didn't have time to look at mine today, chased 100 miles to buy a replacement vehicle for my CR-V.
