Should I use cheaper parts not made in the U S A ?

Good sound advice, Harold! I always use AC Delco parts for my GMs and Motorcraft for my Mercury. I advise people to do the same but usually get told I'm wasting my money. I do make exceptions when needed because of the age of the vehicle and the unavailability of Delco or Motorcraft parts. Like in 2018 when I had to replace the BCM on my '94 Fleetwood. The Delco BCM is no longer available so I bought a Cardone unit. It's been fine. Sometimes you have to go aftermarket. But if the OEM part is still available, that's what I get. The Delco battery in my 2003 S10 Pick Up recently had a birthday, it's 5 years old now and still going strong!! Thanks for your input!! Jim
