2. Draw a straight line on the bottom of the car connecting the two 1/2" lines.

3. Use the lines as a guide to cut out the rear corner of the car. This is where the Tungsten Bar will be installed.

4. Cut 1/8" off of both ends of the piece of wood that you removed from the car block. These pieces will be used to fill in the sides of the weight.
