LCA doesn't look right

I think you missed the point....being that an alignment is an easy way to know if it's a problem that needs fixing, and there aren't many other ways to concretely measure it out. :D
No I didn't miss the point and I'll stand by my statement. My method and a tape measure, since he probably doesn't have a tram gauge, will confirm what he's already thinking. No need to put it all together and pay for an alignment then fix it.
