How to check rear differential fluid in a 73 Cuda

Hi. Sorry for the dumb question. But when I picked up my 73 Cuda 340 out of storage this spring, and there was a puddle of grease on the floor.  It was right under where the drive shaft enters the rear differential.  I drove the car home and checked the following day to see if it was still leaking - and it wasn't.  So either the seal is now working or I am out of grease.  I am pretty sure it's the original stock rear end.  So how do you check the fluid in the rear differential?  I was trying to feel for a plug but couldn't find one.  Thanks!

on a  8 3/4 rear?  See the square thing sticking out of the passenger side... remove & fluid should just ooze out

I see the plug you are talking about.  Thanks.  If no fluid comes out, I am assuming you fill it until fluid starts to come out.

Also, thanks for the great picture. It really helped. I was looking for the plug in the wrong place.

This is why people who own classic vehicles need to own, and study, the applicable Technical Manuals.  I spent many years in the Army trying to get soldiers to do that, and now, civilians.
