53 chev, I feel your pain. I have the d.s. a bit lower than the right side. I have tried all sorts of things and all the measurements of what was done check out. I feel like the chassis is twisted in some what when it was a work truck in the 30's. I even put a new set of coil springs on the front end a couple months ago. The old ones were not off much and the new ones are dead on ......still a little "lean" to the driver side. Heck, I'm gonna drive it. Most folks will never notice it but.....I do!!
