1) Vehicles Built Before 1983 - Standard Hangers
May require 2 new holes to be drilled into the frame inner gusset to accommodate the
replacement RS hanger drilling pattern.
2) Replacement Hangers - Heavy Duty Design
Should be used in sets, i.e., if the right-hand front hanger is being replaced, the right-hand
rear hanger should also be replaced. This is due to the mounting height difference.
The replacement hanger is " thicker than the old hanger.
