so i just drained the oil out of the differential of my 240z, and i cannot figure out where the opening to put the oil into, any help there would be much appreciated

So i have a 73 240z, that wont start. the solenoid clicks, but then the starter doesn't do anything. i know that started works but cause i jumped the positive over to start the block. any ideas on common things that go wront and what not. ive been playing with it for a while and haven't come to anything thanx
