I have a 7.5" rear with traction-lok and 3.08 gears on my '84 5.0L and i think it was in '86 as lx mike said that they switched over to the 8.8". The 7.5" in my '84 has lasted 150,000 miles and i've done a few large burnouts, but i garauntee that if i went to a dragstrip and dumped the clutch at 4,000 or if i did anything with sticky tires like slicks that the rearend would blow up (axles shafts would strip, or bearing bolts break, or gears stipping, etc. etc.). In '87 Ford finally got the GT and 5.0L LX right by making them pretty heavy duty in most senses with the higher torque capacity World Class T5, 8.8" rear, bigger sway bars and brakes and previous year things like quad shocks (from '84) and sport valved struts and shocks as well as more aerodynamic styling.

fastang - quad shocks were first used on 7.5" rears on 5.0L models in mid-84, i've still got the stock ones on mine. the 2.3L 7.5" rears don't have provisions for the quad shocks (i think) and usually have higher gears like 3.45 or 3.73.
