Steering column is hitting the headers and melting the plastic

Mark the column on the engine side of firewall where
it passes through the plate and once it’s out cut the outer tube square to leave about 1 1/2” out past the mark. Next remove the bolts from the plastic bearing support and remove it from the cut tube. Next split the short piece of the outer tube to remove it then slide the bearing support up the end of the tube and mark for the holes to bolt the bearing support in place.
