Unilug wheels - which lug nuts to use?

My "new" Western wheels are unilug.  I've done some reading, and know that you can get offset (or center) hole washers (depending on the desired lug pattern) with shank lug nuts.  The offset washer fits in the recessed countersunk area around the lug hole.  Well, on my "new" wheels, the area around the hole is not recessed or countersunk.  It's flat, along with the rest of the wheel surface.  Any idea what I need to use?

My Uni-lugs have the recess for the washers, but yes I am running the shank style lug nuts.  No issues here.

My E-T 5 spoke wheels I originally had on my '76 were unilug. I never had an issue (other than the blasted occasional 2a.m. flat tire and the really trying issue of being buzzed and making sure the oval spacers stayed in place while getting the lug nuts on and tight. Then, as the wheels aged and the corrosion set in, you would get tiny cuts from the flaking chrome in the recesses trying to fit the spacers in place.

Wait, that really did suck...

 most mags use this style lug nut :
                                           


 e.t.'s and keystones with the oval off set insert, use a special type nut and insert ( if the insert has an angled seat... you need the short shank with the angled seat... never use regular nuts with those type wheels, as the stock type nuts don't catch enough thread to hold properly!):
