you will be hard pressed to notice 1/4” or even 1/2” difference, but need to be sure what you are referencing from…. checking true squareness of a chassis is cheap but no small task, it’s about (old school way) setting up string control lines, one down the center of the truck, then to create a “square” string box around the truck, then measure from there…
I took one my vintage race cars to a body shop so they could check squareness, LF was 3/4” back……………tough to fix…..
