Installation Procedure
1. Cut the replacement windshield pillar section in corresponding locations to fit the original panel. The sectioning joint should be trimmed to allow 1
1/2 times the metal thickness at the sectioning joint.
2. Create a 50 mm (2 in) backing plate (1) from the unused portion of the service part. Trim the backing plate as necessary to fit behind the
sectioning joint where there is no reinforcement.
3. Drill 8 mm (5/16 in) plug weld holes along the sectioning cut on the remaining original part. Locate these holes 13 mm (1/2 in) from the edge (A)
and spaced 40 mm (1 1/2 in) apart.
IMPORTANT: In any area damaged beyond recognition, or if structural Weld-Thru adhesive is present, space the plug weld holes 40 mm (11/2
in) apart.
