You may be able to drop the pan by supporting the engine with a 6×4 long enough to span the inner fenderwells, and use tie down straps to hold the motor up so you can drop the k frame enough to get the pan off. I haven't done it with all the stock steering gear still in place, so it might require dropping the drag link and disconecting the steering wheel. This is assuming you have a stock k frame of course😀
