So, I would advise you to drill out the stock relay rod, not bother with the idler arm, since its extremely unlikely that you will break it. I won't say impossible, but thats the way I'm leaning.
I would carry an inner and outter tie rod end, and one or two adjuster sleeves, as they are the weakest part.
Yeah, my line of thinking is the same, just wanted validation. :-)
