P/S idler arm swap?

[Chevy Fleetside]

I noticed that if you bolt up the steering box first it give you the right angle on the idler arm. Before I knew about the REZ kit I just drilled some holes and bolted up the steering box with some spacers. After I used the rez kit I had to redrill my idler arm again as it angled back about 1/2". I welded a piece of 1/8" metal to the back of the first hole I drilled and filled the hole back up and then drilled a new hole. can't have oblong holes holding the idler arm.
