They do tend to develope a bow in them, measure across the shock towers to see. If you can’t get a good set of dimensions from one of the local companies I may have some at home. And they also d fatigue crack, check for those around the welds and in the virtical areas on the ends. I know the guy who did mine several years ago welds in some reforcements but I don’t have a diagrahm showing exactly what he did.
