67 mustang rear end width?

[justin51986]

I am in the market for a 9" rear for my Mustang, I found one local, but am unsure if it will work for my car. I have 67 coupe that I am mini tubbing, and have the TCI 3 link rear suspension, can I use the 50" housing without getting into my frame? I know this is probably a dumb question, but i'm still learning all this suspension/drivetrain stuff. always been a body man and am trying to self-teach myself the rest. thanks for any insight!!
