Classic Parts of America (still Chevy Duty in my mind and when Googling):
- excellent on-line catalog
- good selection
- excellent customer service
- free shipping on $300+ order is a GREAT deal
- excellent customer service
- ask them if they still give a free hat or shirt with $300 purchase
All these are excellent in customer service (no nonsense return/refunds):
