I am considering putting independent suspension under my '49 Ford coupe. Can anybody that has used these things recommend if there is a specific year/s of T-Bird that would be best to use? I want about 3.5/3.7 ratio and traction lock (or whatever they call posi in a T-Bird) to use behind an AOD. I don't care whether or not is has disc brakes as I will use whatever it comes with. Any help would be appreciated. Thanks.
