hello: The trans drain plug is on a flat plate at the bottom of the trans, and is a large allen head, I am not sure of the size, and the fill plug is on the drivers side of the trans and is also a large plug, I had to use a suction tube and hose to fill it, as for the rear end I am not sure, I used the Redline MT-90 for the trans and it is running and shifting great on my 79, sorry I do not have any pictures of the plugs. Hope this helps. Steve
