Combat Rim O-Ring Questions

[hndrsonj]

I know there is a 10 bolt and a 20 bolt combat rim for the 5 ton. I believe the 20 bolt uses a big triangular ring. The 10 bolt uses about a 5/16" round o-ring. What uses a smaller; maybe 3/16 or 1/4" round o-ring? I am sorting through a box of o-rings and am stumped to what they are for.

Is it 20" or 16.5"? HUMVEE

I'll take some out of the packages and measure tonight. What did the A3 use?
