[oletrucks] 3-Point seat belt installation question

["Stephen" <slb1@humboldt1.com>]

I am installing Juliano 3-point seat belts in my '58 Fleetside.  Juliano's
told me to cut out a section of the door pillar outer surface the exact size
of the mounting plate. Then weld  in the plate so in fits flush to the
surface.  Is this correct or is there something more solid deeper in the
pillar to weld the plate to?

Thanks,
