How do you cut an opening between cab and box on cutaway?

To cut an opening between the cab and box on a cutaway vehicle, first ensure the vehicle is securely positioned and that all necessary safety precautions are taken. Use a reciprocating saw or an angle grinder with a metal cutting blade to carefully cut along the desired line, avoiding any structural components or wiring. It's important to mark the cut line clearly and take your time to ensure a clean cut. After cutting, smooth any rough edges with a grinder or file to prevent injury and to prepare for any finishing work.
