Mach 1 rear end???

Hey guys, is the rear end in a Mach 1 any different other than gears, than my 02 Gt? better axles? better posi? brakes? I have a chance to pick one up for a 100. bucks with low miles on it. If its better I'm thinking of getting it and doing a set of 3.73-4.10 in the new rear end. Do you guys think it's worth while upgrade? :shrug:

Thanks Ram:SNSign:
 
Is it the whole rear end, including axles? For $100, I'd definitely pick it up. As was said, the main difference is the 3.55 gears, but also don't forget that the axles are already set up to accept the larger cobra/mach1/bullitt rear rotors.
 
It's mine

I bought it today after work, it's complete and clean. I take note and weld it up and put some gears in it. I'm hoping by next year this time it have some boost. Time to start saving.

Guy's thanks for all the help and advice, I'm sure it won't be the last time I ask for help.:nice:
