61-71TruckHeaders

• Due to various manufacturing designs, aftermarket parts, engine configurations, suspension combinations, etc... TTi cannot ensure headers and exhaust systems to fit all combinations. However, we have done our best to accommodate both factory and aftermarket component combinations. In some cases, slight modification or repositioning may be required on your part to clear the specific situation.
