Idler pulley

[ravinshield]

This might be a stupid question but are all 99-04 idler pulleys the same. I will need to replace them on my 04 cobra soon. Also does anyone know the total smooth and non smooth pulleys i will need. Thanks

I don't think so. Only the terminator has an 8 rib belt which would generally mean a wider idler. All the idlers(4) are smooth.
