small block 727 question

Hi guys-
Does anyone have a picture of the inspection (or dust) cover for a small block 727 transmission? I need one for my 69 Dart 340 car, but I have no idea what it's supposed to look like. There are a few on ebay, but like I said, I don't know which one is for my ride.

Thanks in advance!!!

George

they have 2 small holes and 4 large holes. i think big block has 4 small holes. i will try and get a pic.
