57 NAPCO rebuild

looks like an easy fix.
bear in mind that the original mounts were set up so the cab could pivot on the driver's front mount in order to get hood alignment etc correct. not that your new frame and engineering wouldn't account for that.
curious if you will use donor body mounts, since you may need to move the rad support mount anyway. it would be more modern than the old metal on metal front cab mount and the rubber conveyor belt style rear cab and rad support mounts.
