I just ordered my 33 kit last week and have started gathering some of the parts. I think I have found an awesome rear end and just wanted to verify that all is OK before I buy. I found a low mileage (<50,000) 2004 mach1 rear end complete rotor to rotor for 300.00. All I can see wrong is a light dusting of rust on the rotors. What I've read indicates that this rear end is wider than recommended but it sounds like most people have to use spacers anyway. I am going fenderless. Jump on it, right?
