1972 402ci Oil pan removal

[Kevin1972C20]

I'm in the find a leak fix a leak phase of maintenance and have determined the oil pan gasket to be the problem. I have no means of removing the engine and would like some advice from the pros out there on the best technique for pan removal with the engine in place. Looks like I have about 2-3 inches clearance with the front cross member, but I have no idea if the oil pick-up or crank will be in the way.
