I have a 97 t-bird with a 4.6 V8. Recently the pulley on my AC condensor froze up and broke the belt. I knew this was coming but was unable to get the time and money to fix it. Anyway, is there a way of getting a smaller serpentine belt and wrapping it on the other pulleys on the engine? I ask this because I need to get the car in to have the transmission looked at because there may be a problem with it, but I need to have it working right so I can go take it in. Or, is there a way of making it unstuck long enough to take it in? Or is it possible to get a used pulley from say a junkyard off a car of the same year and out it in myself as a quick fix. I don't want to spend 100 dollars to fix the pulley itself until I know the car is still worth holding onto; the condensor I'm told needs to be fixed if I want AC, which really isn't a problem right now and needs freon.
I want to keep the car, it has about 98k miles on it, but I don't want to spend 100 bucks plus labor to fix the pulley problem and then turn around right away and spend another some of money to fix the transmission and anything else that is going to pop up on me, or even worse it breaks down right after getting it fixed up.
I think it's possible to reroute with a smaller belt because I'm pretty sure that there were cars up north sold without AC. Any help you can give me would be greatly appreciated.

Thanks
