4. NOTE: Where possible, holes should be drilled through the A-Pillar reinforcement and the A-Pillar inner panel, (note that the reinforcement panel is DP600, (Dual Phase), steel and a HSS drill bit will be required). This enables MIG plug welds to be installed through the inner panel, where possible. Mill out the spot welds, it will be necessary to use a HSS spot weld drill bit. 5. Separate the joints and remove the old panel, also releasing the NVH element. Installation 1. Remove the A-Pillar reinforcement part from the ring-frame service panel. Mill out the spot welds using a HSS spot weld drill bit. |
