I'm interested in swapping in a 87-88 Thunderbird rear end in my 90 LX. The reason for this is to do with the increased weight of what I believe to be an 8.8" rear (can anyone verify this?) as well as the fact that it can handle more power. Is this viable swap? I need to know if the rear end is wide enough to fit in a 90 body as well as whether I can mount 16" disc brakes from an SC on it. Thanks to who ever can help.
