I have the 1973 but with the stock 2.4. I do not have to jack up the car as the oil drain plugs can be reached and an oil pan placed under the drain areas with no problem. The oil tank is drained first and I believe thats a 15mm plug. You should buy two oil plug gaskets, but if you cannot check each for damage and flip them over on re-use. The engine oil plug is 17mm.
Everyone is right about the size of the pan for drainage. I had oil all over the floor one day when I under estimated the quantity of oil in the tank. You have an option and that is to dump the oil tank oil into an eight quart holder then transfer to gallon milk jugs for recycling later. Once the pan is empty then go to the engine oil drain for dumping.
Once a year you should remove the engine oil screen plate, remove and clean the screen, re-gasket (paper) and tighten.
Place a bunch of paper towels or washcloth/small towel under the oil filter before removing.
Your going to loose oil removing the filter and you want to minimize oil release to preserve the rubber gasket between the tank and the body. Keep this area as clean as possible.
Use a good oil filter (Porsche, Mahle). Have oil-sorbent at the ready.
Wear latex gloves and prepare to get messy..........
