Russell,
Went out and look at my buggy. The 3 plugs are there....they're small (#6 on drawing.)
Couldn't get a picture of them. Looks like maybe a small allen wrench might work (at least on mine).
Mine is a '73 IRS and has teh plugs as pictured.
I did find this picture in my Bentley manual. Front of car/trans is right side of picture. Plugs are on passenger side partially hidden by frame horns.
