XRAY - Model racing cars

Where can i find them, are they available and what is the part # ?

I have realized that the o-rings sealing the shock shafts are to loose, letting oil out and dirt in, by adding a small washer the orings should squeeze tighter against the shock shaft and keep a better seal.

Imho this is a design flaw and should be corrected, I also dislike the lack of boots at the rear shocks,
because of this my rear shock shafts are now completely sand blasted and will probably wear down the "sealing" orings in no time..

This is why I am going to order two of these: part# 358015 and then add those washers to the shocks.
But I also need new orings and rear shock shafts, the shafts seem to be available, but where can I find the orings?

I've put extra washers in all of mine and I've no leaks at all and no binding before anyone asks

When I was building my shocks up I noticed that there was a lot of play with the O rings against the washers
