A friend of mine wants me to help swap out the stock rear end on his '83 t-bird with the rear end out of an '87 turbo coupe. I guess he can get one for a good price and the 'new' rear end also has disc brakes. While I am confident in my abilities to do the swap, I was wondering if anyone out there has any pointers. I am fairly certain that it should bolt right up. I already told him to get new bolts and bushings for the control arms. My main concern is in the braking system. Will upgrading to the disc brakes require a new master cylinder, or will an adjustable proportioning valve be enough to adjust the balance. Thanks in advance for any insight.
