The front of the pan sits over the cross frame. There doesn't seem to be enough clearence to drop it so that it will come out.
The oil pan gasket is leaking - so I want to change that.
The oil drain plug is almost stripped - I cross my fingers every time I cange the oil - so I want to replace that as well.

Very easy to do and i have an 80
I dropped mine over the holiday weekend, first letting the oil drain for about 12 hours. I cleaned/painted the pan, replaced rear main seal, used the one piece felpro oil pan gasket. Total time was about 6 hours.

Like mentioned above drop the steering linkage, 2 bolts holding the idler arm to the frame is the way I do it. I also found disconnecting the power steering cylinder from its frame bracket gets you a little more clearance. If you have an automatic remove the flywheel inspection cover, on a 4 speed you'll need to remove the starter to get the flywheel cover off. Might not be necessary on the 4 speed if you can bend some tabs out of the way to reach the rear pan bolts, but that's Bubba! Couple wire shields removed helps, there are plug wire clips bolted on with pan bolts.
The HARD part is if you have stock style exhaust with the crossover pipe under the pan. Gotta come off.
The pic is of my 78SA. Also did my white 79, both in the same week. Leaky oil pan gaskets. Luckily everything came right apart!! Low mile cars. 80 will be the same.
