Steering seal kit

Can somebody put my mind at ease? I got a seal kit from Smitty for the steering cylinder/rack and pinion,whatever you want to call it,under the radiator anyway,for the 2-135 White. I had two O-rings left over. Pretty good diameter,not too thick. I took the cylinder apart,started with the piston. There was a thin,flat,blue ring on each end. I changed those,then the quad ring and the ring in the end cap. I put that together,put the new o-ring on the plug in the top of the gear and finally the one on the cap that bolts to the top. Then I saw those two left over. They are just a little smaller diameter than those thin blue rings on the pistons.
Was there a little bit different piston in the earlier Oliver cylinders that used O-rings instead of those blue plastic rings that might be in a universal kit or something?
 
Will they both fit in the groove? I think the flat rings on the pistons are a backup ring for the O-rings. That's commonly done on hydraulic applications. O-rings should be toward the pressure, outside in this case.
 
There weren't any O-rings on there. The grooves aren't wide enough for both. Those flat rings weren't flat in the way that would lay sideways against an o-ring,they were flat in a way that they laid flat in the groove.
 
I had trouble installing the piston back into the cylinder on mine, so put a hose clamp around the blue rings and put in the frig over night, worked much better
