Interesting thread, I have an '85 Bird and just swapped out the 7.5 to an 8.8" LSD, I'm using the Taurus 43mm rear brake calipers and Cobra 11.65" rotors with Fox 5 lug axles. So far I have not connected up any hard lines to the car due to the fact I will be adding the '93 power brake booster and larger MC. I'm also swapping out the front K-Member from QA1 with the longer adjustable lower control arms and using SN95 spindles. Then I have Cadillac ATS/ Brembo 4 piston calipers and 13" front rotors going on. All of this is going to take a while to get sorted out once it is all back together.
