i have a vortech s-trim with the stock pulley. i will be swapping to a 3.33 6 rib pulley and i have a question. when going to a 6 rib pulley do you have to change out any other pulleys on your mustang? all my other pulleys on my car are stock. i am deployed right now and i can not look at the pulleys on my car to see and also i don't have enough time to search for the answer on the web. thanks for the help

All of your pulleys should be 6 ribs so you should be fine. I am thinking this is a single belt setup. You will most likely need a new belt.... maybe not. It's always a good idea to remeasure what you will need. Good luck over there. Hopefully the chowhall is around and you can get better food than mre's.
