restoring a 68 four door . when putting the floor pans in I cut out the brace that holds the pillar (pillar B?) between the two doors to the floor . I cant find it listed for sale anywhere . One guy at a Impala pats website called it a pillar reinforcement . Maybe im searching the wrong name . Just to be clear . the pillar behind the front door that the rear door is hinged to . The brace that welds on top of the flloor pan and keeps the pillar stable. Any idea what the correct name is and more importantly where to buy it ?
