ok... i had a fellow club member tell me about metco pulleys on his GT. i cant seem to find anythin about metco pulleys going on 96-04 GT's at all.. i can find stuff for 05+ cars but nothing for the 96-04 cars... i figured a 90mm idler for a cobra would fit but im not sure.
I've been looking for a cool idler also. Im thinking metco only makes pullies or idlers for 03-04 cobra's and like you said 05 gt's. ask your friend again and let me know!
I run one on our Bullitt off of an Intrepid 2.7L (99-02 or so)
Saves about 6 oz of rotating weight and it's dirt cheap.
On for about 20,000 miles now and smooth as Jessica Alba's butt cheeks.
