I have never changed the drive belts in my 2000 GT, are there any difference between the Dayco Serpentine Belt ($34.44) and the Goodyear Gatorback Belt ($22.99)??? I know many people have had good experiences with the Gatorback, but are they Dayco ones better. Tried a search but came up with nothing, just lots of people saying that the Gatorbacks were the way to go but no opinions on the Daycos. Please help if you can. Thanks ahead.
