If you put some thought in on how that works, If your holes are lined up and the bolt doesn't exscatly go all the way to last one. Not a hard hit but using your judgement it get the bolt to the point were you can start tightning it with the rachet.

Its a method I have used and it has worked fine. Using the other arm to kinda move the lca around up or down while tightning. Just thought I would throw out a idea like he said. I know that the lca are a pain in the ass when your doing this stuff in your garage and air tools are not there.
