I just had to replace missing parts. The parts that i received fit great and were cheap....no adjusting or cutting to make it fit they just snapped together like they were factory made. I am also very pleased on the time that i ordered them and until i received them. Hardly no waiting time at all. I ordered them and 4 days later i was installing them. Thanks EReplacement Parts.
