I have a ‘47 AD 3100 that I believe the PO retrofit a later box to the chassis. I did body work on the right side and added a new angle strip. The left side I simply ordered a new side from Mar-k. The new side fit perfectly.
The issue I’m having is getting the box to measure to specs. The last sill is welded to the original right side. Is the correct procedure simply loosening all bolts and shifting/adjusting the panels so the correct measurements are met? Another words I should just “play” with panels to get it right? Or is there some other point I’m missing?
