NOTE: Do not cut directly along the center of the weld line. Leave enough material on the front side of the weld centerline to allow the remaining weld and frame material to be ground back to the front edge of the front mid rail. This is necessary to make sure of correct fit between the frame and the replacement frame section.

NOTE: LH side shown in illustration, RH side similar.

Locate the vertical weld of the front frame to center rail, using a plasma cutter, reciprocating saw or cut-off wheel cut through the frame rail.
