• Cut the new front longitudinal with a hand saw
and it will be butt welded.
• Grind both sides of the welding section of the front
longitudinal and wheelhouse with a disc sander
to remove the paint and expose the steel plate.
CAUTION : To prevent eye injury, wear goggles or
safety glasses whenever sanding, cutting, or grind-
ing.
• Tighten the new front longitudinal against remain-
ing parts with the vise grips and pliers.
• Place a jack under the front longitudinal end and
support it, and measure the positions for correct
setting.
• Set and clamp the front panel in place with the
vise grips.
NOTE: Use of jigs is recommended for correct posi-
