I would confirm measurement from back of cab to center of rear axle. You want the dump box to fit the wheelbase and look right. However, as mentioned before rear axle can be moved to accomodate desired wheelbase,although modifying enclosed driveline may be spendy. This is common practice when installing aftermarket bodies. A local shop that services-install truck bodies could be helpful....Jeff


Just because you have a few Craftsman tools, it dosen't mean your a craftsman.
