LCA Bushings and Other Bushings

this is a informative thread. i have a question concerning the installation of the QA1 struts. on the lca arm end the factory's rod uses a shouldered 5/8 end for a nice fit in the 5/8's lca hole, now with all this precision fit QA1 stuff why is the lca bolt a 9/16's and no shoulder just threads, makes for a sloppy fit. what have you done to address this are is it only a concern to me?
