When I took my pan off two years ago Christmas ('89 shorty 3.0l AT), I had to jack up the engine about 1.5 inches to get the pan to clear the crossmember. I used a block of wood on the bottom of the harmonic balancer, and jacked against that. Worked perfectly. Watch the fan blades, you go any higher, you might break one. I carefully bent mine while jacking, and didn't loosen the fan shroud, but YMMV.
