Years ago, (40s or 50s, I think) perfect circle made a rig that cut ring 
grooves a little wider and squared them up where you could use an over 
width, thick, whatever ring to get the straight up and down side wall 
containment of the ring.  It would also knurl little blocks saying perfect 
circle on the sides of the piston to hold a little more oil and keep the 
piston from rocking, if you had a little too much slack there.  Now, I would 
think the same principle would work here, if you can get straight and square 
in what ever the widest seal width would be. JMHO
